Query: I will NEVER buy a blu-ray with UltraViolet Digital Copy

This is a power grab by short-sighted studios and I will not indulge them with my business. No matter how much I may like a particular film, I will not spend money on any movie that ships with UltraViolet. And I am not just going to let them move my money around - I will also not buy this movie in any digital format or from Amazon.co.uk. This needs to stop.
