They got the Kazaa Pro. Its basically Kazaa Lite, but its not free. Kazaa is trying to take legal action against Kazaa lite (and other variations). That in and of itself is funny, but whats funnier is that people would pay $30 for something they could probably find on Kazaa for free (a crack for Kazaa Pro).
Also, just like I said in some thread a while ago, the RIAA is trying to use the fact that kids can access pornography and that theres child pornography on the P2P services to shut it down.
And while the fact remains that you can get either on the internet alone, my guess is that the government orders all of the P2P programs to be illegal and makes ISPs turn in people who use them since people usually feel stronger about child porn than they do about the RIAA's problems.
