For those who were unaware, several rumor-oriented web sites posted information about an Apple project code-named "Asteroid". The sites posted drawings that were allegedly stolen from Apple, in violation of non disclosure agreements.
The owners of the web sites never signed any NDAs, of course. They were given the documents by people who took them from Apple (or from people who got them from people who got them from people who took them from Apple....)
Anyway. Apple filed several "john doe" lawsuits against the unknown parties that leaked the documents. Then they tried to subpoena the web site owners for the identity of their sources. The site owners refused, citing California's shield laws that guarantee the media the right to protect its sources. Apple countered by claiming that these are not legitimate news sources.
Well, the judge upheld the web site owners. Media is media, and journalists of any caliber can not be compelled to reveal their sources.
