That's crazy!
It reminds me of how I always laugh when services like Airbnb force you to state if you're in anyway a US citizen or related to a US tax payer. But I guess it's not so funny if you actually are a US citizen and can be financially hunted throughout the world.
So from what you write it's seems like the citizens of the land of the free have to cross the pond with their projects to set them free. And not deal with anything related to Americans at all?
Many banks abroad will refuse to open accounts to US citizens. Not exactly the land of the free, however still free compared to most places.
