I avoid Microsoft's cloud on principal alone.
I use Windows for *gaming* and the availability of anciliary applications. Most of my real work is on Linux VMs or "in the cloud." Why would I want to expose my data to more footprints than necessary?
I have a Google business subscription; I use that instead. My issue isn't one of how badly the company involved might snoop; my issue is having too many fingers in the "data archive" pie.
