The more I hear about companies shifting to focus on AI the more it makes me want to start a direct "successor"/"competitor" company that does what the original company did without shifting to AI. As a bet on the AI enshittifying the original company so much that they either cannot develop the software any more and have to start anew, or that they create so many errors and chaos that they get fined & sued into oblivion, or both.

I think you're on to something here. For a multi-product dev company, they could (if domain still available) brand as 'without.ai' or 'no.ai' or 'sans.ai' and do 'taxware.sans.ai', 'todo-mvc.sans.ai', 'basecampclone.sans.ai' etc..
