I'm not aware of any major project forks due to it, only smaller ones, such as this fork of Waybar that was specifically forked to remove the AI code added to the main project.

Forking the bigger projects would be a pretty huge effort. If enough left at once it could be viable, or perhaps a fork could be cut down to make it more manageable to maintain and develop for a smaller team.

If there is no forks, maybe the dissenters from the major projects will congregate toward independent projects who have already taken a stand against AI.
