Yeah, the solution to that is to mandate accepting cancellations via a single click (or preferably even email, since it shouldn't be my problem if I don't remember my account details when I want to cancel). Disputes should have been the backstop to incentivizing the market to making cancellations easier, but things apparently didn't pan out that way. So arguably, the free market has had its chance, and it's time for regulations.
