Last I checked, the most effective way to pirate content is via a protocol such as Bit Torrent which requires you to also distribute pirated content. And that has legal ramifications, which then requires non-trivial methods to obscure your activities (paid proxy servers, etc). Most of us use Netflix not for ideological reasons, but for the pure convenience of it. Compared to Bit-Torrent,with Netflix you can easily browse titles, watch a bit, switch to another one, or watch whole seasons without waiting for multi-hour or multi-day downloads.

Paying for a DRM-encumbered service is not really consistent with a "firm belief in being DRM free".
