A third is for Office, a third for cloud, and a third is Windows.
IMO Microsoft is a trillion-dollar company because of their long monopoly with Windows. It's so entrenched that their "punishment" for abusing their monopoly position (according to the DOJ) was to give all schools free copies of Microsoft Office, thereby forcing every parent to own a copy of Microsoft office to be able to read reports from their kids' schools. Ingenious!
You know why they would fuck with developers? Because developers have choices now, and Microsoft doesn't like it when anyone has a choice besides Microsoft. They are remedying that.
Why would they fuck with their number one audience, developers?
