"The only actual effect of DRM is that it makes it so I cannot use my Linux box to watch Netflix and I'm a paying subscriber."
At one time they used Flash, and for all of the swiss cheese flaws in its implementation, it actually achieved the goal of having something that ran on all major OS (Windows, MacOS, Linux, maybe even Solaris once?) and could do enough DRM-ish stuff that companies were happy with it as a solution to getting people to use a paying service instead of torrenting it.
But then they decided to use Silverlight as apparently Flash was not secure enough (in DRM terms, they care not one hoot about your security) to keep Hollywood happy. Or maybe MS paid someone to try and embrace their new and long-lasting technology, who knows... Add to that Apple's decision to kill flash on mobile, and Adobe's utter inability to fix it for any sane length of time, and we see Flash is dying as well with only an old version support on Linux (unless you let Google slurp your privates with Chrome).
So we are back to the situation of not having support on many platform (older Android, Linux, Windows XP, etc) and it is easier to torrent. Any how many tears do I see being cried over this?
