It's a bit funny to be like "federation is what will make this great" and then "federation blows us up, so we're turning it off".

It's still pretty bad, but not as bad as it was even a couple of months ago. I suggest using https://rpilocator.com/ to try to find a pi of your choosing in your region. Looks like US stock is still quite limited.

To be fair, I don't trust infosec.pub, reddit.com, or any of those servers. I just choose what I'm going to publish using them with that model in mind.

I think the whole "ActivityPub makes it impossible to really delete things" is a whole nothingburger anyway. If you post something to a public website, like it or not, there's no way to delete it with certainty. The internet never forgets.
