Law firms have motioned this week to represent plaintiffs in class action suits accusing Apple of colluding with publishers. Grant & Eisenhofer claimed to have an insider that revealed "detailed knowledge" in March that gave it reason to pursue the case. A matching filing from another firm also pointed to a source, possibly the same one, that attended an "in-person meeting" with a "very knowledgeable and important confidential source" that was aware of dealings.
