It won't. You know it won't. We're all hoping for it - because of all of the repercussions - but there's too much at stake, for the lobbyists, for the DMCA to be stricken down, even though it's an obsolete, atrocious piece of law.
I dunno. At this point, the DMCA is interfering with the revenues of major corporations. Netflix is now the biggest "network" on "television" and the DMCA is what kept them from partnering with Facebook back when they tried that whole "qwikster" bullshit. Amazon and Hulu benefit from homogenous licensing and the patchwork reinforced by the DMCA fucks them over. Not only that but Amazon's decision to allow you to download streamed content for use on flights or whatever is, if I'm not mistaken, already in violation of the DMCA. The DMCA was entirely about Napster and now that the industry's darling is Spotify, the approaches of 1998 are proving a hindrance to industry rather than pirates. After all, torrenting is down, the music industry has effectively abandoned ownership, the motion picture industry is focusing on franchising and event viewing, and the broadcast industry is pursuing multinational streaming on-demand. The DMCA advances none of those causes. When the DMCA came out, the previous caselaw was the video tape act of 1984. That was 14 years previously. We're now 17 years away from the DMCA; I can easily see someone patching that shit up.
