Agreed. In addition to the factors you outlined, another reason behind the success of Linux in enterprise is Java. Java essentiallly enables people to ignore the OS altogether. So in essence, Linux becomes a dumb platform which can, in theory, be replaced anything else as long as it supports Java. Android is the same story. It may have Linux underpinnings, but that is out of convenience, not necessity. It has no bearing on the actual applications. Google could replace it with something else (Fuschia if it succeeds, or anything else like BSD, or technically, even Windows) any day with almost no effect.
