Threads was also aiming to fill a vacuum left by Twitter. A vacuum that I suspect doesn't exist for TikTok users in the same way. There's a category of user that wants short form video, who started on Vine, did not move to Twitter after Vine was killed, and then ended up on TikTok. TikTok's success seems to be in part specifically because those users did not want (at least originally) a text focused social network, even one that had reasonable UX around short form video.
