When i started buying movies on itunes, people told me it was a bad idea. That i "better keep the hard copy downloaded because apple could take the movie down at any time if licensing agreements change". Is this true? Seems to me like apple may take down the "for sale" version of a movie if an agreement change, but not the "icloud backup" type version that plays on our appletvs for people that already bought it. I know alot of people with appletvs that buy movies and shows and never even use iTunes. They just click "buy" on their atvs and expect it to always be there. What do you guys think?
