There are whole areas of human existence which are protected by laws, and in no way data can be pushed into external (US-based) machine.

Sir, would you be OK with sending all your medical records to US to be potentially mined for profit by for-profit amoral organization like Microsoft? It may help, although 3rd parties like NSA will eventually access them. No thank you. What about your litigation papers at court? Fuck hell no. Just do your job that I pay you to do, doctor/lawyer.
