Quite crazy stuff, usually nothing happens for those who make these copyright claims even if they are false. Copyright claims pretty much hurt only those who have their videos claimed, they lose views and revenue, they have to try to fix it and even if they go against the claim it's up to copyright claimer to decide if they take the claim off or not. Only way to fight against false claimers is going court or at least threaten to go to court.
I can't fanthom how they could have decided to copyright claim these mv's though, it's not obviously theirs and all these companies have enough power and money to sue them. Maybe it was technical mistake, some kind of algorithm?
