At your part about the xbox division, even though there is no such thing called the "xbox division" within Microsoft, that doesn't mean that you can't talk about revenue and profit in relation to the "xbox division". It's just a name people give to everything xbox encompasses, from hardware to 1st party software to third party software to XBL. Now I'm fully aware that we will never know specific figures for this "xbox division" because it is mixed together with a bunch of other things, it still makes sense to talk about the "xbox division" when discussing financials, unless you want people to say "I'm curious as to what the xbox part of the computing and hardware segment, combined with the xbox parts of the Devices and Consumer segment made this quarter" instead of just saying "I'm curious as to what the xbox division did this quarter."
TLDR It makes sense to use the name "xbox division" unless you're gonna start talking about specific numbers, because MS isn't exactly transparent when it comes to the Computing and Hardware segment of their business, so any numbers you use will be pulled out of your ass. There's no need to be overtly difficult about such small semantics.
