Second, threads posted by me and a few members of the Threads team will be available on other fediverse platforms like Mastodon starting this week. This test is a small but meaningful step towards making Threads interoperable with other apps using ActivityPub — we’re committed to doing this so that people can find community and engage with the content most relevant to them, no matter what app they use.
What happens if you merge the user base of a small network and a huge network? https://en.m.wikipedia.org/wiki/Network_effect Will the small network gain from the huge one or the other way round? Also there is a lot to gain. The users base of the fediverse and it’s infrastructure grew by 5x in the last two years: https://fedidb.org/ Meta has a big interest in extinguishing a competitor before it profits from the bandwagon effect.
Active users went down, though. I don’t think mastodon is a big competitor for Meta, Twitter and TikTok are.
