If your recommendation is that every corporation use RHEL or some other version of Linux across the board, best of luck to your in your career! Again, Microsoft OWNS the enterprise systems market. I’ve been in IT over 20 years with experience in every size shop from mom & pop to Fortune 50, and I can tell you that Microsoft is the go-to across the board.
RHEL, Novell, Citrix, etc. don’t have enough of a presence anywhere to put down Big Blue. Enjoy your ignorance of sales facts.
I've been in computing since 1967; and, I have done things that you have not even dreamed of with machines and processes you will never know. I'm still current. You are but an ignorant child, crying out for your wretched employer, the one that always goes, "Wah wah wah!"
Enjoy your ignorance of technical facts. May your chains weigh lightly upon your wrists.
