Google is no longer your friend but you can use it to search for an extended set of results ... history of breaches, their need to know, and verify, exactly where your physical location is, weak crypto - still using SHA-1, shady management with no information about themselves, their practices, security readiness, reassurances/insurance etc. in a country known to have 'extremely close' relationships with the US SS and MIL depts.. No thank you.
