I guess the premise is that it is easier to identify AI-generated content, with a low hit rate (?) of correctness, than to identify correct / incorrect answers based on merit alone.
Also StackOverflow is kind of gamified (a rare case of it working IMHO) and the rules of the game don't work so well when kind of good looking content is easy to generate. SE answers are hard to verify but easy to write. If writing becomes too easy, it is a recipe for spam - as has indeed happened.
