@woodruffw I love your quote above that commits you to your open source base and I'm rooting for you. But how about an approach that commits you to this sentence in a more rigorous and legal way, and spin off your open source tooling to a separate community-based entity? Of course, upon that you can continue to maintain sufficient representation to make Astral's commercial products the natural progression and otherwise the model remains the same. That would be a significant transfer of control, but it is that very transfer that would get a overwhelming response from the community and could really unblock these great tools for massive growth.
I work a lot with LLVM/Clang and whilst i know Apple and Google are significant contributors I feel confident that LLVM itself exists outside of that yet accept that e.g. Apple's contributions afford them weight to steer the project in ways that match their interests in e.g. Swift and Apple tooling.
