I’m not sure about your first question, but for the second: Mastodon and Lemmy are both part of the Fediverse, implementing the ActivePub protocol. But what each offers is not really compatible with the other. Mastodon is microblogging, whereas Lemmy is link/news aggregator. The semantics of each also don’t match: does favorite-ing in Mastodon post equal a Lemmy upvote?

So while you can’t natively cross-post between the two systems, there’s no reason why an app can’t integrate the experience of both seamlessly. And in any case, sharing content from one to another is as simple as including the URL.
