This just seems like a bad faith comment. Is there ANY example of a user raising a legitimate concern like this and getting banned for it?

This reads like cheap, low-effort bashing.

this just seems like a google-faith comment.

Google has cheap, low-effort customer support, so I'll allow it.

Wait, how does that help? Low quality customer support hurts us. Low quality comments also hurt us. That just doubles the hurt for me. It doesn't compensate in any way.

It's like some guy punching me saying "For the Green Team!" and then you come by and punch me saying "For the Yellow Team!". Like, dude, you didn't undo the first punch. I'm now twice-punched. I want to be zero punched.

Google's (Youtube's specifically) automated processes have allowed the rise of extortion via their copyright systems using the threat of automatic account deletion.

Their automated processes do result in account deletions, and they intentionally build their systems so it is hard to reach humans to resolve complaints, so I don't think that comment was particularly undeserved - I read it as jokingly superlative.

They'd probably accidentally suspend the actual serial killer's account instead.
