For those that dont understand why people are so pissed off and are talking about terms and condiciona Think about It this way:
Let say you subscribed a magazine/service
One day you recieve a letter/email saying that the magazine/service is no longer avaiable.
But you didnt remembered of revoking your credit card authorization, but no biggie, since they are dead, they wont charge your again.
A few days later, you recieve a letter/e-mail saying that the /magazine service have been restarted, and they already charged you the subscription fee, whithout even asking you about It.
Would you think It is ok?
Spot on!
Bingo.
