#Prediction: if #Threads follows through with #Fediverse support by using #ActivityPub, and especially if #Wordpress and #Tumblr join the party, #ATProtocol will be all but dead. AP will be the standard for social online, regardless of any benefits of AT. #BlueSky will effectively die with it, unless they switch to AP (unlikely as then they’d just be one instance amongst many). Threads joining the Fediverse would hurt BlueSky (and to some degree #Twitter) a lot more than it would hurt #Mastodon.
