The courts have ruled that free porn online isn't an anticompetitive threat against pay sites. Court documents regarding porn are generally awesome for many reasons. For instance in this one, the defendant's lawyer, "in the interest of representing his client, he visited 101 tube-based adult entertainment sites." - but for personal reasons he visited over 300 tube-based sites. Wait - over 100 tube sites? I'm about 40 short. Lawyers have access to all the best porn. The good news is that tube sites remain a competitive part of that "constantly changing commercial landscape" we all know of as masturbating in front of the computer.
