The Electronic Frontier Foundation (EFF) will defend AppleInsider and PowerPage, two blogs that divulged the computer maker’s plans for a product code-named “Asteroid.” The EFF asserts the bloggers shouldn’t have to disclose the source—an Apple insider—who revealed the plans. Apple has issued subpoenas to the bloggers demanding they name the source.

“Bloggers break the news, just like journalists do. They must be able to promise confidentiality in order to maintain the free flow of information,” according to EFF Staff Attorney Kurt Opsahl. “Without legal protection, informants will refuse to talk to reporters, diminishing the power of the open press that is the cornerstone of a free society.”
