What's bullshit about content creators? I enjoy watching documentaries from The History Channel or The Learning Channel. If someone does a bunch of research and self-publishes a documentary, they're somehow less valid?
The article isn't about anybody "making money off the fediverse". It's about finding a way to make the fediverse viable, considering that everybody wants to use it, but nobody wants to donate.
The same way "anyone" could make an HTML5 compliant browser. The reality is you can't do it unless Google lets you.
