Just had a very large client reach out and ask for LibreOffice again after moving to MS Office because they found Excel too difficult to get data in correctly. So they are going to LibreOffice for exactly the reason that everyone claims that "everyone" chooses MS Office... LO is easier to use and has better compatibility 🙂

They own licenses for both, so purchase cost is not a factor. They've used MS Office more time in the last three years. Given less time with LibreOffice and zero "price" incentive, they've chosen it as the superior product for them - with zero prompting from IT. Out of the blue the managers chose it as the better product.
