Hey, no one is trying to stop you from doing that. I'm sure it is very convenient for you.

My point of view though is that automatically uploading my personal files to some corporation computer on the other side of the world should not be the default when I try to save something. Maybe sometimes I'll want to use that feature, but there are a variety of reasons why I don't want it most of the time. And I definitely don't like having to jump through hoops just to avoid it.
