It's true that the monetisation of everything is pretty awful, but it's one of the most important reasons to join a platform for content creators whether we like it or not.

The main reason to join a platform for a creator is the amount of the potential viewers, which of course don't increase much without new content creators. Therefore Peertube needs a secondary reason for creators to join, which it doesn't seem to have.

If anything, joining Peertube will in theory decrease their income, which actually gives them a reason to not join :(
