(Apparently) Unpopular Opinion: I think defederating Threads is the wrong move, because it just locks people into Threads. If people on Twitter had the ability to move to Mastodon AND still interact with all the people they did before, I think we would have seen even more people move. The only reason I still check twitter at all is because I have a few close friends who didn't move. Meta is likely going to have big adoption of people who aren't ready to go to Mastodon, but are interested in getting out of the dumpster-on-fire that twitter seems to continue to be. But blocking those people from being able to join the more popular Lemmy instances, given no actual policy violations, just will keep people in Meta that otherwise could leave. With the "however" being: It's not quite clear to me that Threads users will be interacting with Lemmy as much Mastodon, if Threads were a Reddit replacement, it's more directly connected.
