I think the unnoticed problem is that the tailors (old school system administrators and dev ops) are being asked to become the managers of Old Navy (kubernetes cluster administrators). Their entire skill set is opposed to this new role. I can't really blame them for being frustrated.
To keep stretching my already thin analogy, there are still tailors in this world. However, most people buy their clothes at outlets like Old Navy. Whining about the quality of the clothes and the crummy manufacturing process at Old Navy won't change that.
