• Useless fake spam content.
• Posting AI slop ruins the "social" part of social media. You're not reading real human thoughts anymore, just statistically plausible words.
• Same with machine-generated "art". What's the point?
• AI companies are leeches; they steal work for the purpose of undercutting the original creators with derivative content.
• Vibe coders produce utter garbage that nobody, especially not themselves understands, and somehow are smug about it.
• A lot of AI stuff is a useless waste of resources.

Most of the hate is justified IMO, but a couple weeks ago I died on the hill arguing that an LLM can be useful as a code documentation search engine. Once the train started, even a reply that thought software libraries contain books got upvotes.
