This has to be the most idiotic thing I read this week.

The original idiocy here is the DMCA, this and the other idiocies practised in its name are consequences. Over time the idiocies build up as case law precedents until new and ever more egregious cases are made, some of which stick (as in throw shit at the wall and see what sticks) and the cycle continues. Eventually the only way to root it out becomes new legislation.
