Generally I’m presuming that threads is sucking up lots of people who are alt-social curious. They may have just drifted to doom scrolling there.
Seems to be affecting BlueSky too. Plenty of Brazilians joined, but I’d bet plenty more joined threads.
And I’m not sure it’s spoken about enough. With Threads, big-social just artificially segregated the market (is musk/Zuck really a choice?) and are sucking the oxygen out of alt-social.
It’s imo THE issue with the threads embrace.
