Companies like Netflix are stuck between a rock and a hard place. They'd sooner do away with DRM as it adds significant cost and complexity yet only serves to inconvenience their users. However they're forced into using DRM by the content owners who argue that such measure are required to protect their content.

This is why their position on DRM is often left unspoken, they can't publicly discredit because they need the studios on their side. But equally it's hard to address the criticisms if they also agree with such criticisms. So it's easier to just avoid being drawn into the argument to begin with.
