The thing is, sometimes you need Microsoft not of your own volition but because of bureaucracy. When I was signing a contract recently, the government required me to fill in a office word document and it would not work at all on libre, I had to scramble around the house, went through 3 different computers trying to get any of them to have office working after I just recently uninstalled it from all of them to use libre only, but in the end I had to use a university computer to fill in the doc.
