It's a win/win for Microsoft and the alternatives. More people will pay for their software, so Microsoft will keep their revenue stream intact.
However, more people will look for alternatives, Apple and Linux. Linux will be the big winner.

Microsoft knows the model well, it worked for them in the early days of the PC when you could steal all the Microsoft stuff you felt inclined to steal.
