I haven't really used a WYSIWYG word processor in almost a decade (I like Pandoc), so these are old memories, but I remember feeling like the interface to OpenOffice (before it was split into LibreOffice) was more intuitive than MS Word 2007 and beyond. I feel like they doubled down on 90's-era MS Word-style interface, which I personally have just found to be extremely intuitive and easy to work with.
That said, the equation editor for LibreOffice and OpenOffice utterly sucks. This bizarre, quasi-TeX, quais-WYSIWYG interface is extremely unintuitive and hard to work with. The equations themselves generally render fine, but back when I used OpenOffice on Windows I purchased a copy of MathType and would OLE equations in. This didn't work on Linux, which is why I stopped using LibreOffice.
The good news is that most state workers probably don't need advanced features like an equation editor, so hopefully this transition won't be super painful. Seems like it would be rough on academics though.
It's the main reason my dad (who isn't an academic but does work on R&D in the aerospace industry) won't touch LibreOffice. He's constantly bothering people to see if he can use one of their Office licenses because he hates the LibreOffice equation editor.
My handwriting is completely illegible, even to myself most of the time, so ever since I was a teenager I would type out all my homework, including math homework, so I've developed pretty strong opinions on math formatting. I've gotten good enough with TeX that I don't really have anything I can't easily do, but my dad has, for reasons kind of unknown to me, has had a strong aversion to learning LaTeX, despite the fact that I have offered dozens of times to teach him, so he just sticks with MS Office.
