Do you think Meta's Threads app will be beneficial or detrimental to the Fediverse?
Personally I believe that it'll make people associate the Fediverse with Threads, which is not a good thing. Edit: It'll replace their definition of the Fediverse, with Threads, and people may widely forget about Mastodon, Lemmy, Kbin etc.
And that is not a mistake or a missing feature in a beta version. People can easily join but they can't leave. Threads can only grow. And the will remain this way until someone wins in court against Meta
