That kind of works with smaller players (a random thai TV channel dinging people incorrectly is probably going to get some sort of time-out, and even if not, going to court against a smaller player like that is probably within the realm of possibility), but the big players have too much leverage. If Sony gets threatened with even minor punishments, they can simply say 'Fine. But then you have to remove all videos featuring gameplay from Sony Interactive Entertainment's games, or else we'll sue you for copyright infringement'. Even that example is fairly narrow and something that Sony is clearly allowed to do within the current bounds of copyright. They could go full nuclear and demand anything even vaguely related to Sony and its cultural hoard be taken of Youtube, and Youtube would have to comply, if nothing else, while the fight in court goes on.

Youtube has very little leverage, and Google/Youtube is very invested in not ending up in court over this kind of disputes, and the corps making claims know that.

The only actual fix is reforming or abolishing copyright.

I’d love to see a similar three strikes enforcement of bogus claims. N strikes and the copyright immediately enters the public domain. Pick your battles very carefully.

Seems intuitively difficult to implement changes to the law to get this, but I can dream.
