Perfect moment to plug !Peertube@lemmy.world
Growing steadily, and in my opinion, definitely a way to supplement (still far from replace) YT. There's actually some neat content on there by now, from just good to fascinatingly bizarre - but almost always very genuine and authentic. Especially when comparing to some years back, it really has become a proper seed for a platform instead of a novel experiment - but more people interacting with the content and/or supporting the creators would be amazing as the next step.
Oof, that sucks. Seems like someone else needs to create an open source alternative app. The platforms themselves are libre software, right? I couldn't find a lot for loops on that, but Pixelfed itself seems to be.
