The point I'm trying to make is that you don't have to be able to read non-microblog stuff (Kbin threads, PeerTube, Writefreely, etc.) on a microblogging platform and that it's probably best for Mastodon to not have that functionality. Many people on Mastodon are going there for microblog posts, not threads. They want a Twitter alternative, not something that's also a Reddit alternative. Conversely, people on Lemmy & Kbin aren't making threads for people on Mastodon to view and interact with, as they're platforms for different types of content.
If you want to be able to cleanly view both threads & microblog posts, there are platforms that allow that, but I don't think Mastodon needs to or even should be one of them. If you make Mastodon support all these kinds of content from all these different platforms, people who go to Mastodon for a Twitter alternative will wonder, "Wait, why is there stuff from the Reddit alternative? Wait, I can see things from the Instagram alternative too? Why's that? And I can see full blog posts?" Mastodon, being an introduction to the fediverse and sought after as a Twitter alternative, shouldn't do all of that.
