perhaps "This is a requirement for any premium subscription video service that wants to interact with popular studios because if you don't interact with popular studios people don't view your service as premium."
Premium = big name movies
Big name movies = big name studios
Big name studios = full of corporate bigwigs who dont understand that DRM doesn't stop piracy
"This is a requirement for any premium subscription video service" -- this is blatantly false, unless you redefine premium to mean "requires DRM", in which case it's circular.
Also note the use of "protect" as if it was a positive or good thing.
