I dont think what you say there contradicts what I wrote. Rather you bring another and new issue in play. It's not only about, Do you "own" your film or are you really "renting" it?
Look at Amazon and kindle. They not only can switch your book off whenever they want. More significantly, they collect all the information they can - what you read, how much you read, what words you needed to look up in a dictionary, your annotations, your bookmarks... In 10 years time, that will be films too.
PS sorry digrssing a bit there, I'll stop now!
