The issue I’ve run into is primarily compatibility with existing documents and being able to share it with other in industry. Like it or not, for business in the US, the office suite is pretty much the only document & spreadsheet application you can expect everyone to have.

It’s not fair to ask people who aren’t interested in learning linux to deal with the incompatibilities between Libre/Open office and O365 because “I don’t like Microsoft”. If they’re pushing to move away from MS and understand this, I’d still probably recommend LibreOffice over OpenOffice because moving someone from a well maintained industry standard Microsoft product to a less supported and less compatible Oracle app seems irresponsible.
