I don't think so. How would they kill the fediverse? Like there will still many communities that will not federate with Meta and still continue to operate as usual.
Most people using Mastodon right now are not following mainstream people on their feeds - they are mostly following like-minded people who have made the switch from Twitter. If their server decides to federate with Meta, it will actually improve their experience because they can start following mainstream people from the comfort of their Mastodon feed. And if Meta decides to break ActivityPub (which I doubt), it will be back to the original status quo for most users.
And most mainstream people will not be signing up for Mastodon anyways, they will be signing up for Threads/Blue Sky.
@app_priori@jacktherippah I would never put anything past Facebook's intentions and the reactions of some Mastodon users. I think a good chunk of Mastodon users would still go back to a centralized network and might see Threads as a way to have both worlds ... until the other shoe drops.
Well that's because Mastodon has many shortcomings. Like the search sucks. It's hard to find people to follow without asking people for recommendations. Mastodon is scarcely a Twitter replacement; it feels like it was built to create extremely insular communities. Like Gab and Truth Social run on Mastodon's software.
@app_priori I sular communities that can federate. That's the draw for me, but may not be for others. I think I'm done with a Twitter-like experience but I know a lot of other Twitter "refugees" just will not roll with the new experiences. And recreating somewhere where news and information can be diseminated. I mean it seems like it would be an easy technical problem to solve and I'm surprised that it hasn't happened already.
