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.”
And if that experience ends up being negative, instances can choose to defederate. Many admins just want to see if it will actually be a problem. If admins choose to solve a problem that doesn’t exist yet, let them. But let’s not protest instances and destroy communities over possibly nothing just because the admin is curious to see what happens.
