@zetabeta @pluralistic "YouTube sucks" is not an answer to the question "why is PeerTube useful".
Since step 1 of using PeerTube is "first have a website that is already capable of hosting video" I still don't know the answer to that.
There are many reasons that YouTube, Instagram and TikTok are popular, but the gating reasons on which all other reasons depend are: trivial signup, and "free" hosting.
