How is expended computational power (to encrypt) relevant for the bandwidth bill though? I understand it's an expense for them, but (1) 7500% is not a correction in measurements (they must have noticed that over 2 years if it actually costs that much) and (2) it's a completely new expense category (if your plans are bandwidth-based, you can't just force someone into a larger plan when bandwidth stayed the same, you should announce and explain the change in plans).
