For many of us OO/LO meets our needs.
OTOH For corporate use: MS Office is the winner because of the world wide supporting infrastructure.
How many places can (prospective) Employees get MS Office training (and/or be certified)? LOTS
Now, how many for OO/LO?
IMHO Linux suffers because there are too many distros, each with their quirks.
Corporate (and even Small Business) does not have the resources to train the average worker to use Linux (or the in house version).
Couple that to the lack of specialty tools (apps) once you get away from the basics. EVEN MAC owners run into this. Or Apps that don't run under emulation <If you emulate Windows: you are sort of running it and can't claim to be a PURE MAC user>
W7 took Windows close to where I wanted, then W10 took a lot of control away from me. While this may be good to keep systems better secured for the masses, it also makes it difficult to keep a non-vanilla one running .
