I'm not knowledgeable about sex work at all, but a lot of the discussion I read noted that it seemed troubling how OnlyFans had so much authority over how the content creators did business. It's not uncommon to hear how sex workers or people in the adult industry are at the whims of opaque moderation on social media too. [2]
Sex work can be an exploitative industry, but I think federation could bring a lot of power and control back to the content creators involved online.
Disclaimer: Again, I'm not an expert on the topic of sex work or knowledgeable about it at all. It'd be a lot better to get feedback of the people involved or know the industry better.
