The victim is to blame. Microsoft's behaviors are well-known, so victims are to blame if they continue to use Microsoft platforms. CFD computation does not in any way require a Microsoft OS.
"Your shop runs SolidWorks? Don't worry! There's nothing intrinsic to CAD that requires a Microsoft OS. Switch to Linux!"
Implementations actually matter. Hordes of us would jump ship if we could, but convincing vendors to port flagship software, or even do something as seemingly straightforward as a license migration is never easy.
How many of these customers have actually bitched out their vendors for not porting their software to non-MS OSes? None?
Sorry, I have no sympathy. Look for alternatives, or roll your own. Or find a new line of business altogether. Whining about your OS vendor abusing you is getting really, really old now. Like an abusive boyfriend, they're not going to change, so it's up to you to make a change.
