Honestly it isn't. Nothing about the Fediverse is private or inherently secure in that way. Everything is public. And you should assume that everything you publish through activity pub could eventually be looked at by anyone. If you want private or secure messaging there are non-activity pub open source secure alternate. In fact signing up for Lemmy there's even a field to enter for one. Whether or not a server federates with meta. Meta is still going to data mine the ever-loving shit out of all of them. The point is. None of us are at Meta's wim about being flooded with their toxic content.

Honestly I want to see meta flooded with our content. So much anti-threads anti Meta sentiment. Actual leftists. And not just make believe right-wing liberals who've been conditioned to think that they are left. It would be hilarious to watch Meta try to play wack-a-mole sanitizing everything. To please their reptilian corporate overlords. And if you don't care and just don't want to see it. You can always block them personally. Why let them data mine in peace. I say we make them work for it.
