Why don't I see Threads.net posts in my home feed?

Before you comment, please know that I'm not complaining. Someone asked this in Mastodon and it's a good question because if you don't block Threads dot net, then you can look people up and follow them and vice versa.

In my home feed I see posts from other Mastodon servers but not from Threads. Why is that? Thanks in advance

Edit There are no Threads dot net posts in my Global feed either. And I haven't blocked Threads either.
