Apple never said anything about open-sourcing FaceTime. Jobs said they were going to make it an open standard. That’s very different, but it doesn’t matter because they didn’t do that, either. My understanding is that patents got in the way of the plan, but according to engineers at Apple, there was never any actual “plan” to do this. Jobs’ introduction of FaceTime was the first they’d heard about making FaceTime an open standard, too.
