Proponents of open video have potentially won a battle here, but I have to agree with the commenters that say that this may just push the content companies to add new controls elsewhere in the content ecosystem. For example, DTCP (and particular the IP-oriented DTCP-IP) is already widespread in newer "TV Anywhere" style devices. It may also have cryptographic weaknesses, but compared to HDCP it is even more closed and it is controlled by an independent cabal of corporations.
