@poetgrant It's "industry standard" and it's hard to break that mindset. But I am on the same page as you. If only there were alternatives that were as "complete" as Office365.
Yes, you can argue that LibreOffice is better until you're blue in the face, but until LibreOffice begins to offer corporate-level support and the majority of techs are familiar with it, tough shit I guess? Also, I'm sure a business would prefer Office365 alone compared to using two solutions: LibreOffice+Thunderbird
