Which could still be millions?
sharedInbox handles this.
mastodon.social sends a single federation activity to www.threads.net’s sharedInbox. threads’s internal systems handle all the visibility and routing to followed users and whatnot. the same thing happens in the opposite direction for threads->mastodon (or whoever).
now in theory this is an optional part of the specification and you can in fact send one activity per person if you really want to, but considering how widespread it is you’d have to be intentionally and explicitly malicious to not use a sharedInbox if the remote server indicates it supports it.

You know a lot about the infrastructure of activity pub.

no, not really.
i have attempted to build my own federated stuff (none of them actually federated “in real life” though) so i did read the specs but quite a lot of these are from my memory and if there’s anything i know is that my memory fuckin sucks lol

I think you’re sincere about wanting to federate. I don’t agree at all and I think you’re being naive about them trying to take over, there is a shit ton of astroturfing going on in these threads, but wanting the fediverse to grow isn’t a bad thing…
