Youtube alternatives like peertube need to get their act together and think about how to remunerate content creators. Ain't nobody moving from youtube to peertube that wants to pay their bills with content creation. Nobody.
Why should PeerTube bother with that though? We all know YouTubers won't switch to it, infact, YouTubers will not use another platform ever.
They could just upload their videos to multiple places, but they don't. I think it's clear that the vast majority doesn't actually care about it. So what is the point of trying to appeal to them? They may as well priroritize their existing userbase, who are fedi hobbyists.
What economic reality? Most of their income comes from sponsorship deals and Patreon subscriptions anyway. YouTube ad revenue is so unreliable that pretty much no content creator I follow considers it a primary way to make money. How could uploading your videos to other platforms in addition to YouTube have a negative impact on that?
