I'm not sure this worked out as well as we thought it might do for the musicians.
for example, adding support, bug fixes, corp-friendly licencing and pricing models, private code/package repos, code/package signing, etc. Providing biz ppl to be available for meetings, legal protection, PII, etc.
To foster goodwill, they could even send some of the profit back to the original maintainer, ala pikapods: https://news.ycombinator.com/item?id=31312682
People who don't want tiered licenses could definitely just mit it and walk away of course.
I do like the idea of paying back the original maintainers otherwise people could sandbag projects to fork them later.
