"Have you ever tried to hire a secretary to use Linux + LibreOffice instead of Windows + Word?"
Actually, I know of a number of modern-day secretaries who happily use Google Apps instead of MS Office on mac OS and Linux, with zero problems, and one of our clients actually uses Softmaker Office on Linux as standard desktop platform, and here, too, no problems.
And why should there be, being able to adapt to new/other variants of the software used by your trade is a basic competency expected of any employee today. Especially considering the constant change MS Office and other MS products are seeing. If that's too much for you then you might want to consider a career change to flipping burgers.
"Remember most users are not computer-savvy. Just change 1 little thing and most will panic and be lost."
And yet millions of "not computer-savvy' people have no problem handling constantly changing user interfaces on apps, smartphones and IoT, and many of them don't even use Windows but mac OS.
Which proves that the notion of people panicking because of minor UX changes is nothing more than utter nonsense.
