They can also get that data without doing anything because any data they’d get from federating is already public.
No, that’s not how it works at all. All of your public posts are already public anyway, Threads doesn’t need to be involved for literally anyone to go through all of your posts right now.
You can choose to show “Subscribed” communities—only the ones you’ve chosen, “Local” communities—only the ones on Lemmy.World, or “All”—which will pull from all the communities federated with Lemmy.World.
So to answer the question, posts from outside your home instance will show up in your feed, should you choose for them to.
