Actually, they're hurting an independent content creator over something she has every right to do using works in the public domain. Youtube is doing that, not the fraudster making the false claim. They have no power other than what Youtube gives them, and Youtube gives them 100% of the power.
Have you ever tried to report fraud to authorities? Even if you show overwhelming evidence, details of perpetrator, chances are LE will laugh you out and say it is a civil matter.
Only if you're a big enough company and/or have to the right contacts. Do you think regular people could get the police to raid a data centre or something on grounds of copyright infringement?
no, but a 10YO troll in Brazil sure can get the FBI to raid the home of an American streamer they don't like.
Not saying it's even by any means, but it's better than zero human response. There will at least be some case in a govt. record should some bad actor keep getting reported, unlike Google.
As you don't want to risk 3 strike, you agree to share revenue.
Basically Youtube doing nothing.
