Conceptually, at "worst" I think it's a minor feature that most people have found work arounds for.
Technically, they "can't" enforce quotes against non-Mastodon clients but non-Masto clients would have to consume quotes from others, I imagine. I work in/around data so I'm just applying my education to the unknown. I could be absolutely wrong.
The Fediverse on which Mastodon sits is based on many different tools. Some of them are "mini-blog" type tools similar to Twitter. Mastodon is the most famous of those by a long shot - but it's not "the" fedi, just a planet in it.
