Remember when you decided to buy, rather than rent, that movie online? We have some bad news for you – you didn't.
Biologist Anders Gonçalves da Silva was surprised this week to find three movies he had purchased through iTunes simply disappeared one day from his library. So he contacted Apple to find out what had happened.
And Apple told him it no longer had the license rights for those movies so they had been removed. To which he of course responded: Ah, but I didn't rent them, I actually bought them through your "buy" option.
At which point da Silva learnt a valuable lesson about the realities of digital purchases and modern licensing rules: While he had bought the movies, what he had actually paid for was the ability to download the movie to his hard drive.
