I think the biggest factor in that is getting tutorials and such out there that focus on the basics, written by people who mainly do things on Linux using the basics and GUI tools. So much of the Linux content out there is focused on power users and even the tutorials for new users tend to be written by those power users who may have been tech focused before switching and forget or just don’t know how basic they really have to get to not make people feel intimidated. Given the right distro/desktop environment, and there’s plenty of good ones to start with, people can use Linux almost just how they use Windows. They just need someone to show them how without pushing them to do everything in the terminal too fast or going immediately to scripting as a solution to problems.
I don’t think it will ever happen, but the way PeerTube as a whole would be able to rival YouTube is when looking at all instances as a whole, or a large number of federated instances sharing content. That distributes the content storage and bandwidth to help ease things up and expand the amount of content available/searchable on each instance. Kind of like how lemm.ee was made to help ease the load from other bigger instances of Lemmy such as lemmy.world. The closest a Fediverse platform has gotten to actually posing some real competition to a mainstream platform was Mastodon compared to Twitter/X, but even then it wasn’t just one instance but Mastodon as a whole.
That said, doesn’t Bluesky run on something like a federated model?
Meet the new boss, same as the old boss. Tired of government censorship, whether it’s left or right wing. They both do it, and it sucks either way. Then both sides will “champion free speech” when they’re not the ones in power.
