I think most of the complaints are that Microsoft Office doesn’t work. Which is true. The web version of Microsoft Office is honestly kinda terrible.

And no, people don’t want to use a product that does the same thing as Microsoft Office, they want to use a product called “Microsoft Office”. No, it’s not logical, and doesn’t make any sense at all but it’s how people are.

The only sense it makes is that M$ hasn’t followed the spec, and so things done in office display fine I’m say libreOffice, but not the other way around. So if you’re company is willing to transition, but everyone you deal with outside the company is still on Office, there’s a bit of a communication issue. That’s M$'s biggest strength, homogenous work environments.
