Earlier quoted context omitted.
End users don’t care about decentralization — it’s not a feature, it’s an implementation detail. Unless PeerTube beats competitors on UX (both for viewers and creators), why use it?
Creators have been pissed off about ContentID for nearly a decade now, but until recently there wasn't a good enough alternative to YouTube.
(For the avoidance of doubt, I think PeerTube is great technology and I hope it wins, I just don't think it has any chance of supplanting Youtube any time soon).
