their platform, their rules
if he is so business savvy, would have launched his own platform
My guess is that he or someone else will, but the new US administration will make it very difficult, they will attempt to shut down any platform that allows any dissenting opinion.
The social media platforms get certain protection under the law currently because they are not classified as publishers, by censoring and editing they are acting as publishers, and they are specifically censoring with a political bias. FFS they don't ban the ayatollah of iran! They didn't ban anyone supporting the BLM protests in the US in which multiple people were killed, and many beaten.
Then they are also acting in collusion with each other, one platform (e.g. Facebook) bans someone and then another (e.g. YouTube) bans them also.
Apple and Google currently provide the two main App stores, and pretty much have a monopoly. YouTube, Twitter and Facebook start to ban people based on political bias, consequently those banned people and their followers move to another platform (e.g. Parlour), so the big tech providers remove the alternative apps from their app stores.
It is reminiscent of book burning in the 1930's
