Lenni's video affected Josh severely due to his Asperger Syndrome. People with ASD are known to have problems with sensory integration and filtering stuff out.
Dedsec's videos tend to default to black and white, and and most colors seen tend to be muted or otherwise easy on the eyes. They use glitchy, flashing graphics to induce discomfort when pointing out things that should make you feel uncomfortable, but never to the point of actually triggering anything in the person watching the videos. The sound modulation used in the videos also lowers and rounds off the pitch of the sounds used in them. Sitara understands how far she can push her art style without triggering Sensory Overload for Josh.
Why does DedSec always get followers no matter what they do or how violent their actions? Because Dusan is giving them the majority of their followers at the beginning. He just wants to lull them into a false sense of security. Afterward, they're a bunch of outlaws and those who follow them are the kinds of people who want to know more about them. There's no such thing as bad publicity after all.
The high prices for DedSec's firearms and gadgets is because all of them are 3D printed to order, even the military ones. Even if the blueprints were procured at no cost to DedSec, the cost of the material used to print the weapons is far from cheap.
Watch Dogs 2 no longer has Focus and gun takedowns like in Watch Dogs. Marcus is more hacking-oriented and is usually not the combat or killing type of person; in contrast, Aiden Pearce is a professional and experienced killer. Focus is a reflection of Pearce's reflexes and gun takedowns reflect his willingness to kill his enemies.
The use of Umeni as the security agency employed by most of the companies DedSec come up against makes sense when you remember that the Breakthrough DLC for WD 1 states that some, if not all the original founders of DedSec were former engineers for them (presumably for security systems) were scapegoated and rotted in jail, which led to DedSec's founding in the first place. Before Blume, Umeni was DedSec's orignial enemies.
Why did Enforcers go from heavily-armored glaciers in the first game to often being a fat man with a Kevlar vest? In Chicago the majority of criminal activity was organized around the Chicago South Club, which had the entire city in its pocket and could easily manage to sell such gear to their criminal allies. By contrast, there is no real central criminal authority in San Francisco, meaning that the gangs need to gather what they can.
A little fridge makes one appreciate how Josh played Lenni even more. The way she was squeeing over the nanotech and practically bouncing out of RenSense with it says she may not realize her new toy is disabled until she gets it back to her home base and has herself shot up with it. In the mission proper, the other DedSec members comment that the homeless people RenSense had been experimenting on would pass the now-inactive nanotech naturally. Which means that Lenni, to borrow Wrench's interpretation, will end up "pooping robots" for the next few weeks, literally flushing away hundreds of thousands of dollars' worth of bleeding-edge experimental tech she never got the chance to play with. "Don't fuck with the Hawt Sauce", indeed.
DedSec's name has multiple meanings, depending on what you take it as short for.
Dead Security: Whatever security you put on your secrets may as well be dead. Give them time and incentive, and they will find a way through and find out what you're hiding.
Dead Sector: A technical reference to an unreadable sector on a hard drive. DedSec operates through anonymity, and a big part of their campaign is preventing their members from being profiled by ctOS.
Marcus's proficiency in melee combat (being able to take down even Enforcers with little effort using the Thunder Ball) might not make much sense at first when one compares him to Aiden, since the former is more a hacker than a vigilante, until you remember that Marcus was raised in the rough part of Oakland. Growing up in an area like that, he would probably have learned to fight in order to protect himself.
DedSec's main Hackerspace under the tabletop games store isn't just because they're nerds. Such a store would sell miniatures, which in turn give them a cover so ctOS doesn't tag their excessive purchases of the resin for Wrench's 3D printer!
The version of Car On Demand used by Marcus undergoes several significant changes since the verision Aiden had acess to, being able to repaint the cars as you wish and call in cars during operations. Aiden's version of COD is a black market contact, stealing whatever car they can find of the type Aiden specified and are unlikely to be willing to help while Aiden is on a mission because he is usually going up against serious criminals, Blume or the cops, with Aiden's contact unwilling to get caught up with the mess. Aside from a select few, the cars Marcus have access to are purchased from Car Dealerships meaning thatthey are actually Marcus' cars, so Marcus can easily have them repainted. As for the delivery, it is likely that it is done by other members of DedSec, who would naturally be willing to involve themselves in DedSec operations.
There's a Spider Tank in the game as part of Blume and Tidis' "10 Year Plan". Considering that the first game is set in 2013 and this game is in 2016, with the whole Digital Trip thing, how long until the US government, under Blume's orders, were ready to deploy these things on civilians?
Wrench hates animals. It's implied he had an abusive childhood. Begging the question, did his parents hurt his pets? Did his parents' pets hurt him?
DedSec has, by the end of the game, crossed: The NSA, Greystrom, the FBI, Blume, the Church of the New Dawn, a couple of insurance firms, Haum, Nudle, the Sons of Ragnarok, the Bratvas, the Auntie Shu Boys, the Tezcas, a prominent politician, and the douchebag leader of a pharmaceutical giant. They've made a LOT of enemies and very few friends. It may require going underground like Aiden Pearce to survive.
They kind of already are underground. Also they didn't cross these groups, they took them to the cleaners, New Dawn certainly was basically ruined, and the Tezcas were massacred, while they may be angry at the crew, it's equally likely that they are the ones who are afraid, or should be...
They also pissed off the US government. DedSec are cyber-terrorists at this point, they've jumped to that level after what they did to South Korea. The Feds in Watch_Dogs may be dirty, but they aren't stupid and have infinite resources compared to DedSec cells.
T-Bone killed eleven innocent people when he shut down the power along the Eastern Seaboard. How many innocent people died when DedSec shut down South Korea's power grid?
Consider the Whistle-blower side quest's bad ending for a second. Even if Jason jumps presumably Ded Sec are going to release the data they had to exonerate him. Furthermore his method of suicide isn't exactly the kind where you find him dead hours or days later when someone comes looking or the smell draws attention, we instantly find his body, with other people surrounding him, so his family will be told exactly when he killed himself, right after speaking to them. Can you imagine how it would feel to have driven someone your care about to suicide, when he'd actually done nothing wrong.
When investigating the Zodiac Victim at the Dam you can hack a phone beside her, which is shown to be infected with the Zombi 2 virus. Assuming that the phone belonged to the victim, does this mean that her death was in part caused because she tried to call for help but couldn't because of the virus?
How does Wrench's mask work? He doesn't appear to have any buttons to control it, and it's too thin to have any kind of facial tracking. Also, while we're on the topic, how does Wrench see out of the thing when his eyes are covered by LED screens?
A pressure-sensitive layer on the inside using microswitches would be feasible; as he smiles, frowns, or whatever, different parts of his face would contact different parts of the mask. A given contact pattern would trip a particular emote on the display. Granted, realistically, ironing the bugs out of the software responsible for filtering out spurious results (such as while talking) and reliably mapping them to an emote would be a nightmare if not outright impossible, but that's why we have Rule of Cool.
As for visibility, that's at least straightforward - the goggles section appears to have a structure similar to a fencing mask. It's like looking through a window screen, but your visibility is at least decent.
Looking a little harder at the mask reveals that there's a webcam built into a sort of "third eye" position. He likely has it providing a feed to the inner side of his mask's goggles. Facial recognition software, something that's far more advanced in setting, could also account for triggering his mask's emotes.
Computers require a lot of cooling to keep the components functional. That's why they have heatsinks and cooling fans, and that's also why a computer will immediately power off when overheating; to protect the hardware. So how was Marcus able to do anything in the conduit, where the temperature was reportedly 120 degrees (assuming Fahrenheit), and where you could see the air ripple with heat, without the computer failing due to overheating?
Three reasons. 1) The computer itself didn't start out hot, so it has a short-lived benefit courtesy of thermodynamics as it wouldn't heat instantly, just quickly; 2) He didn't use it for very long - just a few keystrokes, really; 3) He didn't do anything too intense with it. Logic generates heat, the harder the processor is working, the more heat it would generate, and simple tasks generate less thermal load. He couldn't've worked in there for long, but for the brief time we see, it probably would've been fine.
Additionally, that same computer gets submerged anytime Marcus goes for a swim, shot at whenever he comes under attack, crushed when Marcus falls backward onto the couch to sleep and save the game, and a host of other things that would have damaged or destroyed that laptop in real life. This is an Acceptable Break from Reality, so the player doesn't have to constantly run back to the Hackerspace for new gear every time Marcus gets shot or falls in the bay.
In the news report after the Street art mission claim that "chatter online suggests the Golden Gate Vandal is a member of the hacker group DedSec. The Golden Gate Vandalism reads "Create, Destroy, Rebuild, DedSec", it is blatantly obvious that the vandal therefore is a member, so why the speculative language.
While it could be DedSec, news reports typically try to not jump to conclusions without corroboration. In this case, the graffiti might be so obvious that the news station wanted further evidence it really is DedSec.
In Cyberdriver and Automota DedSec steal one of a kind cars, a movie prop car and a brand new prototype respectively, both of which are presumably very expensive and very valuable, in the resulting police chase the cops use the same violent tactics that they use in normal chases, and can very well wreck the car if they player is not careful. In such circumstances would their priority not be to disable the vehicle with minimal damage, given how valuable they are? Particularly given that, since Marcus can hack into every vehicle linked to CTOS and, among other things, disable the drive function, one would assume that the police, who have access, would also be able to disable the drive function?
