The media industry has already decided that it should be allowed to turn copyright enforcement into a revenue stream and I doubt they're going to stop their extortion racket now.

This ruling could mean that they'll increase their efforts targeting individuals with threatening letters demanding that they admit wrongdoing and settle for a few hundred to a couple thousand dollars at a time or else get sued in court and be forced to pay a lawyer tens of thousands to defend their innocence. It could mean they actually take more individuals to court instead of dropping the case every time they threaten somebody with enough money to hire a lawyer to defend them at trial.

The media industry is also pushing for more control in other ways as well like blank media style taxes which would let them rake in a steady stream of cash without needing to make make specific accusations. They also still want to be able to force ISPs to instantly blacklist any IPs they accuse of streaming copyrighted content. They've got this power in many countries already and innocent users have already been screwed over by it. They may decide to focus their efforts on getting this pushed through in the US now.

I doubt this ruling will lead to the kinds of broad copyright reforms we need, but it's long past time the courts started pushing back on the insane power grabs of the RIAA/MPA. No other industry could get away with demanding what they have.
