> Not even Richard Stallman or Linus Torvalds make money on open source or free software despite preaching it.

I've been paid to produce FLOSS for quite a few years and I know plenty of people who did too. I did not realize we are such unicorns...

It is crazy how much of the tech industry - one of the biggest industries on Earth - still uses so much volunteer labor. Its crazy because in no other industry would people expect you to not only give away your stuff for free but do it in such a way anyone else can copy your stuff and edit it.

Torvalds got RedHat and VA Linux stock options and probably has a very good contract with the Linux Foundation.

I earn income selling copies of free/libre/open source software. Other people could too, if they tried, but they don't.
