This seems to be the mentality of quite a few people about when the webcomic Megatokyo underwent Cerebus Syndrome. The comic basically switched its fanbase from "people who know about shoujo manga" to "people who like shoujo manga and/or character-based plots", so while the quality is still good and the update problem has arguably improved, it did cut a few people out of its main circle. And since these people are those who don't like things...well...
The character of Fanboy in the Magic: The Gathering webcomic UG Madness plays out this trope a lot, mimicking the Unpleasable Fanbase of the game, as seen here. The actual author of the comic, though, is more reasonable, as show in strips such as this.
In particular, that strip is a jab at Transformers webcomic Lil Formers, weekly one-panel gags featuring chibi-style Transformers that tend to occupy the same space as transparent knocks against the first live-action movie, Animated, and Revenge of the Fallen, in that order.
Since then, the author has been steadily updating PROBLEM SLEUTH 2, which you [Jane] have been following avidly. You are happy that he stayed in that lane, and stuck with a time-tested formula. If he went in a different direction, you probably would have found it really disappointing.
Parodied in Unwinder's Tall Comics where Unwinder didn't even like the original books in question, yet he still feels the need to criticize the upcoming film adaptation.
Unwinder: The guy who's directing it is Nathan Blaine. Director of Elite Force Vampire. Amy: Yeah, I remember that. ... Didn't you hate those books? Maybe it'll be an improvement!
Penny Arcade showed this as a rite of passage for Gabe's descent into Dungeons and Dragons fandom because he now had a version of the game to hate for not being the version he started with.
Parodied in San Antonio Rock City: one strip beings with a fan walking up to Mitch Clem demanding that he bring back Nothing Nice To Say to which he says "fine". This is followed by an exact copy of a previous SARC strip with the characters replaced by those of NNTS. The last panel shows the fan appreciating this strip and claiming on how much "better" it is.
