Many of us do not trust Facebook and anything it is associated with or swallows up.
EDIT:
"Instagram head Adam Mosseri said "
““Soon, you’ll be able to follow and interact with people on other fediverse platforms, such as Mastodon. They can also find people on Threads using full usernames, such as @[email protected].””
“We’re committed to building support for ActivityPub, the protocol behind Mastodon, into this app. We weren’t able to finish it for launch given a number of complications that come along with a decentralized network, but it’s coming,” he said.
“If you’re wondering why this matters, here’s a reason: you may one day end up leaving Threads, or, hopefully not, end up de-platformed. If that ever happens, you should be able to take your audience with you to another server. Being open can enable that.”
Threads does have the chance to bring the fediverse into more mainstream acceptance. It may introduce users who wouldn’t otherwise know there are alternatives. The net gain may not be one for you specifically, but the concept as a whole. It may not do that, but it can. And the argument against waiting and seeing being Thread users making noise? That seems farfetched. They don’t hold leverage at all.
In your mind, who holds the leverage in the fediverse if not the users of it?
Defederation is an instance level discussion. So I’d say the users of that instance absolutely have sway. Folks in other instances have literally zero sway. Admins ultimately have the final sway.
