Very good decision.
If you're offended by said content, don't watch!
How do you figure? A person doesn't have the right to censor their own, legal copy of a movie?
That's all these businesses do. You buy a legal copy of the movie and they perform the service of removing the offensive content for you. Just how, praytell, does that violate copyright law by any stretch of the law or imagination?
Well, TV changes movie content all the time, for viewing on the networks. You will never see certain films in their entirety on commercial TV. That said, in theory it is wrong to tinker with the content of a film, just as it would be a book. I hate siding with Hollywood liberals...
