Re: So obvious, why doesn't everyone do it?
"The people working on it are still mostly in the USA"
The point that Rich 2 was making was the wider one about open source projects in general. People contribute to open source from all over the world. It would be very difficult for the likes of Trump to split out contributions from US citizens. It would, however, be somewhat easier to lean on any US-based infrastructure including foundations that support projects. Not that it would make too much difference - the projects themselves would be out from under as quickly as you can say "fork".
