But seriously... I agree. I get that DRM is meant to prevent "casual copying," but right now, that's just called "Downloading from 1337x." Unfortunately, I think that the only lesson movie studios are going to learn from this... is that they should phase out physical media and use Widevine and FairPlay hardware-assisted streaming DRM for everything. Which, to be fair, has been quite more resilient than AACS... but not pirate-proof...
I think the ultimate lesson is that movie studios will never cave on DRM or Copyright. In which case, in an ideal world, we'd repeal DMCA 1201 making breaking DRM legal for private use, and we'd cut copyright to 28 years in length (the original length, and also solving the video game preservation problem). From there, we could just have a trademark protection which states that distributing expired-copyright material in its original state gets a fair-use exception to trademark use, but modifications do not, solving that issue. [I.e. If I distributed Original Super Mario Bros. without changes, it wouldn't offend Nintendo's copyright - but if I changed it, I would have to call it something else and couldn't use "Mario" as a character.]
