I think the way you explained your last point really hits the nail on the head in terms of FOSS. I did actually enjoy large parts of Revolution OS, the movie about the creation of GNU and Linux, but the part that stood out to me the most was cmdrtaco explaining open source (paraphrasing here): at the end of the day you end up working on something you need, and then you think “if I need this maybe someone else does to” so you publish the source code and let others use it. This stuck with me because, well, if I publish something I found useful and nobody else finds it useful, oh well. But if they do, that’s really great! I am not saying Google open sourced k8s out of sheer goodness of their hearts, but I think it’s a lot harder to maintain that sensibility when the project is VC backed.
