Twitter couldn't exist in its current form without billions from billionaires carrying it through years of not being able to fund itself. It would have had to grow slowly, probably in some decentralized form like Mastodon did with people and organizations funding their own instances and linking up through a common protocol. The world would have been better for it.
In a different universe, (for example) branches of governments run their own instances for politicians and candidates to speak on without having to worry about clashing with moderation policies that serve other use cases on other instances.
