I understand the general concept of what Google might do if it was actually doing this, I was looking for some kind of evidence that it was actually happening in reality.

I watch a vlog about EVs on Youtube, and the host of that complains about being demonitized by some new algorithm. I'm fairly sure he's not a fascist that's been put on some list by the Googlestapo, so it seems likely that other people may just be jumping to conclusions.
