A fee is acceptable, if the consumer agrees to it, adobe wants people to pay their agreed on contract, but offer people a discount of 50% of their remaining obligation.

This seems pretty fair to me, when you signed up for the contract, those purchases figure into their operations.

Reverse the paradigm, if they cancelled providing you these services, would you expect a refund, or would it be a money grab to expect to get your money back when they violated the terms of the agreement?
