I suppose the community around a product is also a reason to bring up an influential character's character. You can't fork the community, only fragment it. "I don't want to join a club with that guy in it" is a time when an ad hominem becomes a valid argument.

You can fork, but will you want to fork and spend time and effort, potentially in huge amounts, on that fork? There are reasons to be wary. Choosing an alternative, where that particular reason for forking might not exist, is a valid choice to make.
