I don't think people on the right were being censored at all on Twitter. Things like death threats and racial slurs and misinformation were censored, but conservatives have always been extremely welcome on Twitter and have had absolutely massive followings. Some of the biggest accounts on Twitter have been conservative accounts.
In regards to platforms... nothing draws a crowd like a crowd. What content is on Hive that would draw a big crowd?
I'm glad that Hive overall has gotten away from the mentality that short form content is of no value. The purists of long form content fought with creators for years, called it low quality and that hurt adoption.
That's a good thing that slowly it's becoming more welcoming to short form content. Video is the key. Once 3speak gets shorts back on Threads, that will help. Anything with short form video will draw a crowd. But unless people feel like their friends are here...Not sure what will work to capture the masses.
