Yeah, this is basically true on any other platform as well. While it may be more difficult if everything else is a blob, too, I think the reluctance is more about the audience that uses Linux than the capabilities of Linux itself. People can break the DRM on Windows too.
The reason Moonlight cannot play with Netflix's standard player, by the way, is that Microsoft refuses to license its DRM component for desktop Linux use. Moonlight runs the player on embedded Linux devices just fine, but since Linux is still small enough that MS can get away with slighting it, and since it benefits Windows to keep Linux as incapable as possible, they refuse to allow non-embedded Linux systems to run the module.
Frankly I'm surprised that people haven't cracked the MS DRM just out of spite for this move.
