Isn't Apple's lacklustre support for enterprise fleet management a welcome relief for MS at this time? I remember, among other things, big holes in macOS' LDAP configuration security.
Anything that gets Apple more credible for big businesses should be a big worry @ Redmond. And, if it were to gain traction, it would be a big new market for Apple, all at MS's expense. It's also a small step writing and managing non-GUI Posix code for macOS and and Linux. And IBM announced some biz apps for iPads a while back too.
Windows 8 and 10 have eroded goodwill. Consumers mock it. MS can't afford complacency wrt corporate customers if credible desktop competitors arrive.
