At least for me, OOXML compatibility is the largest blocker - I have some documents which just won't open correctly with LibreOffice.

Though this is becoming less and less of an issue, I still keep Office 2007 in a virtual machine just to turn them at least into PDFs.

"Why wouldn't most companies try to get employees to use Libre Office instead of MS Office? Shouldn't it be sufficient for most people?"

It is, but from experience, people will find a way to complain.

In many countries, there is: you can't be an engineer without ... an actual engineering degree.

I'm an electrical engineer and despise the entire usage of this title by non-engineers.

Most engineers live and die by standardization, rules and responsibility that most so-called software engineers would hate.
