Like seriously, "seems how a lot of software engineers* are ultimately paid these data" (by proprietary companies). Google is a proprietary software company, so is Facebook, so is twitter. All companies that relentlessly abuse users.
Free software advocates meanwhile have a social network with a few hundred thousand active users, they've got privacy-respecting search engines, and have operating systems that don't spy on you.
Proprietary software caused the problems you're ranting about, and your comment reeks of "I work at a company that sells proprietary software and am trying desperately to pin my own sins on people releasing software making the world more free."
I'm nowhere near a free software extremist. Many of the people I find admirable release proprietary software. But your comment is ridiculous. Proprietary software is undeniably immoral.
* "Engineers" is the wrong term because software engineers don't exist.
