I'm now hearing via @rtw and other folks that Microsoft is going to be pushing for subscription-based models for all their stuff (including things like my version of Windows/Office 10 that I paid for and have been paid off for 5+ years).
Microsoft is gonna get pushback on this if they're rolling it out everywhere. Some people will pay, sure. But many will find open source options (easily) like I have before and now will even more.
