How can it be in anyone's interest to remove apps like this from the OS ?
I suspect you haven't been using Microsoft software for that long then.
Here is a possible scenario:
1 - isolate (done)
2 - bar access to any apps but those in a MS controlled shop (probably next, I'm betting on "security" as the argument although that is about the most laughable claim especially Microsoft could come up with)
3 - make them part of an optional package - at an extra charge.
Given the way most corporates bend over backwards to hand MS a lot of money, they'll get away with it too. After all, they have been for decades..
