This has been my single strongest takeaway from this saga: Twitter remains the centre of controversy. When shit hit the fan, Sam and Satya and Swisher took to Twitter. Not Threads. Not Bluesy. Twitter. (X.)
Threads had a rushed rollout which resulted in major feature gaps that disincentivized users from doing anything beyond creating their profiles.
Notable figures and organizations have little reason to fully migrate off Twitter unless Musk irreversibly breaks the site and even he is not stupid enough to do that (yet?). So with most of its content creators still in place, Twitter has no risk of following the path of Digg.
