About your side comment - It isn’t necessarily that they’re being forced to use Office. It’s more that office is the standard that everyone else is using, and therefore the standard everyone expects to work with. If anything breaks or displays incorrectly, it becomes your fault for not using the standard.
To be clear, I hate Microsoft and their monopoly, and the blaming I just described as well. It definitely happens though. Same reason most of Gen Z uses iPhones: if you have an Android phone any problem with phones/chatting suddenly becomes your fault, even if the underlying reason is actually because of Apple.
