I can only speculate, but people can feel resentful toward a technology while still using it. "I need this shitty tool for work but I'm increasingly uncomfortable with its social/environmental/economic/etc. implications."

I think that most of the people who react negatively to AI (myself included) aren't claiming that it's simply a useless slop machine that can't accomplish anything, but rather that its "success" in certain problem spaces is going to create problems for our society
