Won’t the amount of users using meta effectively be a ddos attack on the smaller instances though?
Nope, because Threads users will be visiting Threads, not sh.tijust.works (or mastodon.social or whatever). So even if 10,000,000 Threads followers decide to follow a single mastodon.social account, that account’s instance only syncs it with Threads, not every single user.
why is meta freaking out so hard about instances defederating
Unless I missed something, they’re not. I’m pretty sure they haven’t commented on the topic whatsoever.

Which could still be millions?
LMAO, I don’t think you missed something. There sure are a LOT of people that really want meta here with no benefits listed and only vague reasons why the other is wrong, that sound a lot like sway techniques. There are a few libertarians too, but mostly the first one.

AFAIK, there is only one Threads.net
I hate and don’t trust Meta, so the main benefit for me would be the ability to follow Threads users from my nonprofit, ad free, tracker free, Mastodon account I already have. I don’t want an account with Meta.

That is the first actual benefit I’ve seen, lol. I won’t be following any threads users, so it wouldn’t be a benefit. I also don’t know a single soul that is a threads user either.
That’s not how it works. When you’re federated together, you get a copy of every post on your server. Someone else said that that can be avoided, but I doubt threads will do anything in the other instance’s favor unless they get something out of it.

Nope. Only followed accounts, and only toots made after the first user starts following it.

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.
ShittyKopper@lemmy.blahaj.zone 10 months ago
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
