This is just a byproduct of current events. It's also what tends to happen in other areas of the Fediverse. Like Mastodon, when something really stupid happens at Twitter again (which, tbf, happens a lot these days).

If I'm to guess, discussions will normalise within a week. Some of the users who jumped ship from Reddit are going to go back again or give up on the Fediverse in some other way. That is just an unfortunate reality. But if we've learned anything from Mastodon, the user base will continue to grow at a more stable pace and the "Threadiverse" (Lemmy, Kbin) will become a suitable alternative to Reddit without caring about Reddit too much.
