I wonder with the EU the way it is if the social media space is ripe for a USA only company. The EU has a lot more regulation than the US and a lot less free speech protections.

There are several social media companies that are in practice US-only: Parler, Truth Social for starters.
But if you wanted to make them places that regular people would want to frequent, then it would be pretty much the same product process as complying with EU rules.
