A warning sign of bigger issues in the future
This is also a clear demonstration to me of the dangers of a cash free society dependent on plastic cards/chips/other devices to make transactions and identify you. Imagine a unique form of ID that also served as a payment device and to allow access into buildings.
Now imagine you pissed off some big players like wikileaks has pissed off the governments. The governments lean on the banks, the banks cut off your money, turn off your building access/whatever. The current wikileaks thing is showing this in action today. The ability to remove someone's (or some organisation's) access to the banking world is extremely powerful and here we see again, no convictions, just allegations are enough to do it. Scary stuff.
