It's only a matter of time before the data is leaked, either by incompetence or malice.. look at the amount of data that the Govt has lost before by leaving laptops/USB sticks on trains and the like. Then it will fall into the hands of at best blackmailers and ID fraudsters. At worst a totalitarian government enforcing their own agenda. Scary stuff really.
Secure "no logs" VPN is the way to go... on top of the usual protection too (firewall, antimalware, antivirus, https everywhere, adblock, privacybadger, etc etc).
