Re: Between banks, the UK government and GCHQ.
That's whose job it is to ensure the plebs are kept away from anything actually secure.
You can bet your arse that with GCHQ in the loop NO bank will EVER accidentally recommend, or even accept Qubes, Tails, BSD, CyanogenMod... etc... use any those and your bank will give your savings away.
Approved "secure" systems will be assorted trusty combinations of Microsoft Inc., Apple Inc. and Google Inc. binary crapware. Nothing more.
