Your arguments are formally wrong and they are factual wrong and they are offtopic copy pasta.

It is not a small group that gatekeeps and has negative opinion about ai in games. It is the vast majority of gamers that think so.
To go on topic again, as this topic is not about ai, but about filtering.
Some people flood the market with low effort projects. It's the low effort that makes it slop. And the usage of ai makes it ai slop.
You might not have noticed, but OP did not ask for a filter to filter out ai. This would be trivial, as there is one: https://itch.io/game-assets/tag-no-ai
OP asked to filter out publishers.
