I think the most important part is the idea that it is creating opponents elsewhere.

E.g. manufacturers that badly wanted the relatively non-controversial anti-counterfeiting measures in ACTA must now be furious at all the lost effort and the years wasted because of issues largely unrelated to their own concerns.

If more and more of these companies see RIAA and MPAA's lobbying as increasingly a threat to their own interests, it is going to have very interesting effects.
