Many of us do not trust Facebook and anything it is associated with or swallows up.

"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.”
They will do 100% like that, that they spread everywhere but the posts on threads are only from threads
