Ireland recently created a Basic Income scheme for artists.

Europe should have an equivalent scheme for programmers of important Open Source projects such as this one.

Just German, not European, but still a start: https://en.wikipedia.org/wiki/Sovereign_Tech_Agency

The problem was more than remuneration. It was burnout and mental health issues. They may have been moderated by income but we don’t know.

Also today as I understand it much of OSS is done in-house by major companies (red hat, Ubuntu, ibm, Google, etc)
