Does anyone know why? They are using IPv6 addresses so theoretically there should be infinite IPs.
Honestly YouTube should try to come up with some sort of deal to allow Piped and other third party frontends. Maybe have some sort of paid API access or some agreement to allow YouTube to use piped servers as a cache. The overhead for YouTube is large and maybe they could lower it with community help.
That would make sense(most invidious instances like to rotate proxys and use different backends aswell), but youtube from what I seen doesn't do anything good updates.
They're a legal restriction after all, not a random corporate decision.
That's not true. If it was, the videos would only be age gated in places where it's required by law. That's not the case here in Denmark, to name just one example.
It's 100% corporate "err on the side of censorship" bullshit.
