It happens all the time, a maintainer quits/abandons some opensource project due to economic realities. There are comics, jokes, threads, and so on about what the realities of maintaining opensource software are and that most people are not willing to donate or contribute in any way besides opening issues.
There is a lot of resistance to stuff like the business source license, but people do have to earn a living somehow. Doing so with opensource would be amazing. In lieu of the contested licence, could a template similar to Reminna's actually work? Basically "pay to get this fixed/implemented, make a PR, or it's low priority/ 'I will get to it when I get to it'".

Anti Commercial-AI license
This seems too black and white a prognosis. I think it's not a popular method of funding development because the sponsorship/patronage method seems like it already does a better job of providing stability without making a transactional relationship.
