I heard Google pays its employers quite well. Plenty of FOSS is developed by Google, for example large parts of Chrome.
I think Linus Torvalds gets a reasonable salary. So do many other kernel hackers - payed by all kinds of companies.
Red Hat seems to be doing well, they have plenty of people working in all kinds of FOSS projects.
I already mentioned OpenSSL.
React is developed mostly by Facebook employers. I guess Facebook pays good salaries.
Is that a serious question? Ok...
