It's not like having DRM is really stopping piracy, especially in Netflix's case. For example their new original series of House of Cards and season 4 of Arrested Development were both pirated (I assume using some kind of desktop screen recorder?) and posted online within days of their netflix release. So the use of DRM did not stop people from pirating their content, in only prevented potential customers on other systems, like Linux, from legally purchasing their content.
