For the record, I think they take privacy seriously, however I think allowing an entity to build up that much information on you & your family is inherently risky behavior.
History has shown that laws may target unpopular groups who have done nothing wrong, and well meaning governments can force well meaning companies to divulge information relevant to unjust laws.
It definitely seems a little naive to hand over the keys to your life's data without accepting that you're taking on a fairly large amount of risk with regards to privacy. Even if the party to which you're handing it over doesn't intentionally behave maliciously, you still have to trust that they share your exact opinion on what reasonable use of the data is.
