Looking at the actual story we add Zuckerberg who created Facebook from his dorm room... Bram Cohen developed BitTorrent on his own, using free porn to lure beta testers... Richard Stallman is all about software freedom, he’s not exactly a corporate type... there’s half of the list so far... shall I keep going?
David Heinemeier Hansson wrote Ruby on Rails while in college... Solomon Hykes released Docker as open source in MAR 2013... Knuth did his literary work after his PhD, and becoming a professor, and the books were commissioned, prompting him to do his ground-breaking research... I see only 2-3 of the top 10 who could possibly have been impacted if half of everyone in the field were H1B visas from other nations.
