I agree, but the economics currently don't favor YouTube caring enough to solve this sort of problem In fact, everything aligns to incentivize them not to care: making the barrier to make a successful claim higher and the larger rights-holders start to cause problems; the cost of seriously adjudicating claims is substantial and may well be unsustainable. The consequences of bad policy are also quite low for them: mos…
YouTube doesn't have to adjudicate anything. They just have to demote the known bad actors to using the real DMCA process rather than their own system. They can still make a claim under penalty of perjury with a takedown but that won't count as a strike.
We can speculate to if the current situation is the natural conclusion of those agreements with major IP holders, or if they simply got religion and now embrace those practices... but at least historically, it wasn't simply management discretion which started them on this path.
I don't dispute there are things they can, and should do, nor do I dispute that their current management of the problem sucks.... but it's not quite as simple as just taking a decision to abide by the DMCA as-is.
