It's that, but it's also that AI is not visibly providing any tangible benefit for most people. It'd be one thing if you had to tolerate a datacenter at the edge of town, but at least now you have a robot to fold your clean clothes. Instead, you get the threat of losing your job, the privilege of dealing with AI customer service chatbots, and higher energy costs.

I think most datacenter criticisms are actually coming from people who were going to oppose them anyway. Though a lot of their criticisms are valid, too.
