people see “alternative” and think “competition,” when they should consider it as “coexistance.” so either some youtubers would have to also upload to peertube as an additional option in case of site maintenance and other such trouble, or people on peertube could upload to youtube a week or so later and as part of their end credits/description/whatever, say that viewers can see this content one week early on peertube. It wouldn’t be THE fix for peertube, but more like the first step in a series of ever-increasing tweaks that could lead to this theoretical fix.

Of course, this is based on old practices such as “In theaters Friday, but you can see Thursday at Midnight” and other such strange ad campaigns, so the idea may not be entirely transferable. But that shouldn’t mean someone shouldn’t at least try that and see what happens.
