alt Hacker NewsYou'd pay for it what you paid for it. Did the "Buy" button specify that you were buying the movie or did it say you were simply leasing the film and that it can be removed at any time due to licensing agreement over which you (as the buyer) had no control over?
I think it should specifically say for how long you are renting it. They knew already when the contract would expire, why renting the movie didn't say "rent for 7 years" (or whatever the timeframe was)
