The content is not on the apps - it lives in the relays. The relays can restrict what content they accept. The app is simply an e-reader.

Yea and I can host my own relay that copies all that I post and everyone I follow. It’s not free but it’s a small cost for owning your data. Piratebay is also doesn’t host any files and that is precisely why it still exists
And also to your point, why are we even talking about censoring apps or going after CEOs? 😂
