Whats very interesting about this is the huge implications it could have for adblocking. If the labels win on the 'circumvention' clause, the impact could effectively outlaw adblocking. If youtube can say "you can only access our content with a browser that doesnt save the audio portions of our video" then they can also say "you can only access our content with a browser that shows all ads"

Although google does not appear to be a plaintiff here, they have certainly indicated they could be one in the future ( https://torrentfreak.com/google-threatens-to-sue-huge-youtub... )
