The anti-AI knee-jerk reactions can be extreme, I agree, but at the same time one of important features of Mastodon is that your feed is nor controlled by an algorithm in any way.
So when a company comes, takes those posts and screws with them to create an algorithm to show them, I understand people getting angry - at least some of them joined to be free of that exact thing…
I solved this issue by following multiple tags that interest me. People tend to tag their posts on Mastodon it seems, so discovering posts about, say, wine and cacti is as easy as following #wine #cactus #cacti #redwine #oragewine and so on and so forth - it’s working pretty good for me without an algorithm recommending stuff to me, maybe it’s worth a try?
