The copy protection really doesn't impact me. I don't do 1:1 copes of my blurays. I have a popcorn hour with an internal hard drive. I get lazy. I rip blurays to x265 mkv's and put them on my media box.
I think thats the biggest flaw of the whole thing. For people that aren't like me, they download their movies off the internet. Usually as a videofile, not a bluray disc image. Which means Cinavia becomes useless.
