Dead is probably an overstatement and I agree that the alternative services don't seem to have a lot of traction, at least among people I've followed. However, in my tech circles, it seems like a lot of people (and organizations) just checked out of or way dialed down their usage of Twitter/X and relations. YMMV of course but Musk seems to have been a forcing function for a lot of people to reevaluate their use of such services in general. To the degree that there's a commercial winner, it's probably LinkedIn.
