That depends, watching something on Netflix does not grant you owner's rights in that case. So, DRM is a fair deal in that contract.
As for a DVD that you purchased? That's a different situation. Personally, I agree with you on that one, but you agreed to the licensing terms that likely stipulate you do not own the content on the disc. Therefore, you get your DRM.
