He is right though. Why do you think Windows was so common in companies (on the server side) in Europe at least. Beside the MS lobbying of course, it lowered the initial entry bar, then you ended up with infrastructure completely fuck’d up. Yes, at my last client, we still had 2003 servers running because software deployed on it was done on the “click/click, copy this file” way. I pass on the “clustered” windows servers which never worked succeed a freaking failover.
