Executive Meddling: The whole debacle with the story being put on hold and Kishiro switching publishers was caused by Shueisha editors' attempts to censor the dialog in reprint issues to appear more sensitive — demanding he not use the word "crazy" because "some people who read it may have incurable mental disorders and would be offended." (They suggested "mad" or "angry" instead.)
To wit — they censored the reprints of the manga without his knowledge a few times, then the legal team got him involved directly. They intentionally did this while he was in the middle of crunch time getting chapter 100 out, forcing him to either accept the changes they were "suggesting" or they'd use a clause in his contract about missing a deadline to prohibit all future reprints of Gunnm, effectively ending his career. He didn't notice the former until the latter happened; his response to the entire affair was to demand they recall the edited works and replace them with the "correct" versions or he would change publishers... they refused, so he did.
