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 @mosseri@threads.net.””
“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.”
That not really how the fediverse works. A server can defederate them, but there’s no way to keep them out of the fediverse as a whole. It’s somewhat antithetical to the core purpose behind the fediverse anyway. They can’t commercialize your instance.
I think most people believe that defederating means your messages stop going to Facebook when infact it’s the other way around. Only way to prevent Facebook from seeing what you’re posting here is if they defederate with us which probably is easy to accomplish by having content on your instance that’s agains Facebook’s terms of service and that you refuse to take it down even if they threaten to defederate.
What defederating (if we do it) does achieve however is that it removes all Threads content from our communities which probably isn’t a bad thing either
