I've seen the case made that engineers who develop FOSS don't want to be paid for their work specifically because once they accept payment they feel a stronger obligation to maintain the software and respond to issues from those paying entities rather than focusing on the issues they want to or generally doing work as they see fit.

We all use FOSS - its one of the most unique aspects of software engineering compared to other industries IMO. The world would literally not have advanced nearly as far without it.

I'm incredibly grateful to work in a field that views FOSS maintainers so well and thankful to the FOSS for all the incredible and fun technology I get to use everyday.
