What does the distinction even mean? If an american contributes to a Foss project it is all of a sudden no longer European?
Is Linux from Finland or from the USA? If someting is open source and has a global contributor base and no single entity can subvert it, then I don’t really think the country matters. But it there is one entity that controls it, then it matters where it is from and what jurisdiction and what policies apply on it.
