Office suites are a tricky one. The shitstorm when MS changed it to the ribbon UI was insane. Business users really do not like change. That and the minor incompatibilities in document loading to LibreOffice. I mean, it’s like 99.9% of the way there, but that 0.1% is guaranteed to be in the middle of one of those massive spreadsheets that absolutely fucking everything hinges on.
Still, Office has been going in-browser for a while now. They might at least get off Windows, even if they’re stuck with Office.
