I signed up for Netflix once because I wanted to test how it worked on linux when chrome first added support for it and I had it for about 18 months (never watched it) until my credit card expired because they require you to call to cancel. Don't underestimate how much money you can make off of subscriptions like this. $10 a month is not a lot of money and not worth potentially spending 30-60 minutes on the phone for a lot of people.
