Nah, nearly 90% of mobile users interact with Reddit via the official app (most people use Reddit on mobile devices).

It has graphics and even mouse controls—a whole new game.

The last post is Thelain saying that the forums aren’t very accessible for them and asking if Discord is an option, so I imagine they moved the conversation there.

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.

Short answer is “no.”

Slightly longer answer is: “all of your public posts on Lemmy or Mastodon or any other federated platform are the Public web. So no, it’s not different.”

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.
