I think libreoffice suffers from a branding style issue more than anything else. It's not like Office 365 is inherently superior, but it looks like it is straight out of 2006 and that negatively impacts the users perception of it.

My hunch is that if maintainers were to invest into making it look more like Office 365 (purely in a cosmetic way), the opposition to using libreoffice would reduce significantly.

And for the old timers that will run to "Office 2007/10/13 was the best version and had the old UI". I get it and agree, but the average person likes nice things that look up-to-date.
