I imagine you might want to ping your list on this one...
Dave Cutler was the main reason that VMS learned almost nothing from Unix. He hated that so many of DEC’s customers preferred to install BSD on their PDPs and their VAXen.
He was working on the successor to VMS, when DEC pulled the plug. So he and most of his team went to Microsoft to build NT. Where his arguments with Richard Rashid (who’d built Mach, at Carnegie Mellon, before coming to Microsoft) we’re legendary.
Cutler was a lead developer on Azure.
If he were dead, he’d be rolling in his grave. (Though he seems to have been shuffled off to work on the Xbox, which is pretty much the same thing.)
