It feels like this is intended to spark some sort of frothing outrage, but it doesn't sound all that unreasonable: So... the free business OneDrive and Skype service that came with their product ends when mainstream support for that product also ends three years from now? Yeah, well... okay? Pony up and pay for a service to store your documents online somewhere. It's really not all that expensive. And generally speaking, it's stupid to count on a "free" cloud service lasting forever. Hell, even *paid* services will disappear if they're not profitable enough.
It certainly doesn't affect me with my single license of Office. I don't even use OneDrive features, preferring to use AWS for backups, since they only charge you for the storage you actually use. Last month I paid 10 cents. S3 is stupidly cheap for storing documents and source code backups, since that takes up very little space.
