More of different linux variants actually. Amazon, for instance, provides their own version called "Amazon Linux" which is based on RHEL/CentOS for their aws servers. I've also seen many use Debian for their servers (In fact, Debian/Ubuntu doesn't differ much technically on the server side, but Debian's simplicity and FOSS-friendliness drives many towards it).
Except if one is developing desktop software. Windows is pretty dominant at desktop, especially when considering enterprise, CAD and so on.
OnShape is certainly an exciting experiment. If they pull through financially it will be pretty strong signal, IMO.
