It's not so much an axe to grind as it is a fight for better working conditions. If you had to go look for a job, and all everbody ran is this shitty Kubernetes and Docker, how would you feel being forced to work with that when you knew something better is available, but you couldn't find a job using it because everyone runs Linux, Docker and Kubernetes, because they don't know any better? How would you raise awareness about better alternatives with the goal of creating better working conditions and better jobs?
