Read their privacy policy. They already admitted they will scrape info from 3rd party users/communities which interact with their users.
This is not a good thing.

They can scrape info already. Anyone can set up their own private instance, federate with others, and scrape info from there, and I’d be shocked if Meta wasn’t already doing that. Besides the threads app collecting more data from the people that use the app, they can only collect data that is easily accessible from everyone else regardless of whether threads is federated or not
