As for the ISPs, I imagine the **IAs would love to see them inconvenienced even further by piracy. It means more of an incentive to put in place technological measures to stop piracy like blocking popular trackers, traffic shaping and tiny usage quotas.
Or an incentive to just stop caring and start ignoring the requests from media lawyers.
First, because I don't think that subpoenaing a defendant's identity from a service provider constitutes an abuse of the legal system in and of itself.
The abuse does not come from the request itself, but usually what follows said request. The plaintiff usually knows that he has thin legal ground over his lawsuit and will pull back his suit before a judgement likely to favor the defendants (and set a landmark) can happen. He will then turn around and DIRECTLY contact each of those defendants that got outed in the discovery process and personally extort thousands of dollars from them under threat of ruining them through endless litigation that will cost them far more to defend themselves from a million dollar lawsuit.
Now THAT is textbook abuse.

Are we really sure Skynet didn't become self-aware and declare war on humanity a few weeks ago?
