This is America so you have free choice because we have capitalism.
You can choose not to buy any product you don't like. The studio also has the right to sell any legal product that they like.
What are your options if you want the movie?
1. Buy an iTunes digital copy.
2. Buy a Blu-Ray with UV copy.
3. Buy a Blu-Ray without digital copy.
4. Don't buy the movie.
If you really want the movie option number 4 is just plain stupid. Option 1 gives you the digital copy but not the highest quality. Option 3 gives you the highest quality with no digital copy and this option is often not available. Only option 2 gives you both the highest quality and the digital copy.
I prefer iTunes versions over UV. However I am unwilling to cut off my nose to spite my face.
Also I would like to point out that thank goodness I did not give up on Blu-ray. With my Sony 48 inch Bravia television I cannot tell any real difference between 720 P, 1080 P, Blu-ray, or digital copies. Others might but I can't.
However this week I just installed a home projection system. I have 110 inch diagonal screen. Now I can tell the difference between the various versions. Blu-ray in 1080 P is just incredible.
I bought the Blu-ray hoping someday to buy just this system. Now that I have it I am so pleased!
Refusing to buy the Blu-ray copy just because it has UV hurts you far more than the studio if you really want the movie.
