Yes, but I want an audit log of it all. I doubt they'll ever add this, so I'm not going to blindly trust Microsoft. In my case most files are probably not whitelisted anyway. I download some really huge files sometimes, do those get uploaded too? Do they throttle the uploads and if they don't are they just killing my personal network bandwidth? Like there's too many questions that set me off.
I'm happy with my choice.
