Is that not possible under this license, to upstream a change? It sounds like you can’t put the change into production without it first being accepted, but not that you couldn’t contribute in other ways. I get the spirit of your argument. However, the issue is that companies are not able to make open-source compatible, permissive licenses that allow commercial use due to the new reality that creating a service and supporting a product are the main moneymakers. The code is not itself valuable to them but it is valuable as a holistic system because it’s an already built and adopted and production ready standardization of an idea.
