I have very little pity for any of these customers, excluding maybe small businesses that simply don't know any better and lack the expertise but at every company and client I've been at there were at least 1-2 people trying to convince higher ups to not needlessly build core infrastructure on proprietary components and yet most were and are still being ignored.

Sure, if you have legacy Windows-only software that is proven to not work in other environments, you're out of luck and your hands may be tied but all the VMWare shops I've liberated from this slow, ugly and terrible to automate mess had to pay dearly for that.

How many more rug pulls do these people need? Oh right, they're probably in the middle of some Azure migration anyways.

Some people just need to learn through pain.
