From appearances Apple did not want it's name associated with Digitude while Nokia didn't have the same issue with MOSAID. Now that the connection is out in the open it's going to be impossible for Apple to make denials. What Digitude does from here on out is going to be associated with Apple.
Apple and Digitude conspired to do a two-step deal to make it look like Apple is at a distance. However, the connections between Apple's licensee and the Patant Troll were uncovered.
Apple is now a full partner in Digitude's patent-trolling biz.
