You may not know what advocate means, but it can take steps to eradicate DRM, as if it is really always a bad thing.
Do I think web video and broadcast TV are different? Absolutely; definitely; unequivocally, yes. Obviously. Maybe not for technical folks; maybe not when usenet or FTP trading was your only option for content not music; but nowadays, torrent software and search is really damn easy and free. Broadcast also comes with a landslide of garbage between 95% shit channels and 33% commercial times; Netflix does not operate this way.
I think ebooks and music are totally different ballgames. You'll pay more for an ebook or mp3 album than you will for a month of Netflix; you think they can service you like that without some guarantees to content providers? I really don't know, but I know some of you are up in arms about Netflix having DRM, when it really isn't harming anyone. If you want to own the content, go do that; Netflix is only offering a non-ownership service.
$8 for 24/7, front-running picture-quality, enormous-catalog of content; it has DRM; it _never_ gets in the way of the service; it frankly works so good that owning the content would provide nigh a worse experience. Can you really explain to me the downsides to how Netflix has implemented DRM? What if they offered an additional cost to be able to download content for offline use, which is about the only thing I can conceivably imagine some might have reservations?
