Apple had demanded that OdioWorks remove documents posted by users showing how to make the iPhone and iPod interoperate with other music software.
OdioWorks removed the pages in the face of a legal threat, but is now suing Apple, via the EFF, claiming that the takedown order was illegal under First Amendment rights.
"I take the free speech rights of BluWiki users seriously," said Sam Odio, owner of OdioWorks. "Companies like Apple should not be able to censor online discussions by making baseless legal threats against services like BluWiki that host the discussions."
Apple claims that the documents represented copyright infringement and a violation of the Digital Millennium Copyright Act's prohibition on circumventing copy protection measures.
"Apple's legal threats against BluWiki are about censorship, not about protecting their legitimate copyright interests," said EFF senior staff attorney Fred von Lohmann.
"Wikis and other community sites are home to many vibrant discussions among hobbyists and tinkerers. It's legal to engage in reverse engineering in order to create a competing product, it's legal to talk about reverse engineering, and it's legal for a public wiki to host those discussions."
