Imagine how much revenue Adobe must make from cancellation fees from people who don't discover this loophole. Quietly charging people to leave a subscription while a perfectly working (if ridiculous) workaround exists is a perfect example of an unethical business practice that exploits the incomplete information of customers.
I don't know where I'm going with this. Just had to reflect on how we all agree to denominate value into these fake but useful units of dollars, only for transactions like cancellation fees to be so far removed from the generation of actual, tangible _value_ that it all starts to feel like beta-testing a computer game.
