My gut reaction about lack of content in peer tube is because the platform is ethical. It’s my understanding that popular video platforms started by pirating content, marketing campaigns and other shady things . This obviously is a not a good thing here.

This creates a cascading effect where only people who are more ethical ( rather than less ethical) post videos there. And only ethical ( more or less) people watch the videos there for more or less political reasons ( not national politics but belief how things should happen)

There are probably ways for them to jumpstart content there , but are dismissed, never to be used because it’s against the spirit of the idea. Hopefully someone can solve this by doing something that fits into the vision !
