Although I think the newer generations care a bit less about e.g Word etc and they are also more tech savy on doing hard things on google sheets etc, while the older generations might find it extremely hard to convert from Excel to google sheets etc.
Although another factor is laws etc and privacy policies. Google is much less flexible than office365 when it comes to who owns the data, although of course you have to pay for office365 while for google stuff usually you dont have to pay hence your companies docs might be owned by google and I don't see any sane human being wanting that.
