Rational self-interest of wanting commodity software for infrastructure / tooling. A clear winner means more companies use it, increasing demand for it. Which makes it more valuable to master. If the commodity software is open source, I can learn it at home for a low cost. Then use it at work, again for a low cost. Employers have an interest in using it, as do I. So I want to encourage Amazon, and other tech companies, to use as much open source as possible! Please increase demand for my skillset! Of course, the eternal problem is how the software gets developed in the first place. But I really don't want software that bifurcates organizations vs. individuals to become a cultural norm. Even if the impact of any single case is minimal.
