@youronlyone I don't think they can force the rest of fedi to implement controls on quotes. I do think it's a bad idea to control who can quote post no matter if it's Mastodon or Threads doing it (or even Misskey). But it's just going to be circumvented/ignored easily, like how Masto's "opt-in search" has no effect on Misskey's note search per user.
What fedi really should focus on is controlling replies. And while I have reservations on federating that control, I do believe it's important to give users the power to control how their posts look like in their own instances without having admin privileges. Because it's a (micro)blog.
