Unpopular opinion ahead: I find that demanding money after “voluntarily” contributing to an open-source almost offensive to the spirit of OSS. Money changes the incentives around a community project in an irreversible way. Note that the issue here has nothing to do with financial support.
EDIT: This is regarding the “core maintainers” comment in the linked thread, and not a judgement of anyone’s ability. I gave away years of my own time to open source projects earlier in my career. It was very rewarding in many ways, even financially - what I learned made me a lot better at my job.
Am I not allowed to be ok with that, and believe that a paid contribution model is not ideal for OSS?
