The problem isn't Google punishing actors they deem "bad".

Many of the banned probably did something most of us (and they) deem "shady".

The problem is Google's complete lack of transparency and super reliance on automation.

Google's defense is that they do not want to give out even one bit of information so theoretically some bad actors could assemble a composite model on how Google banning algorithm works.

Ok, but how about giving some sort of reasonable response and some sort of reasonable appeals process?
