According to them. We don't know if apple was ever going to charge $50 for the update to all 3 apps. All we know is that thinksecret and some others got ahold of some rumors that said they were.
And as it turns out they are charging $50 dollars for a box that contains 4 iApps, but you can download 3 of them for free if you don't want/need the media. So basically, I think that thinksecret got it wrong, and rather than admit that they were mistaken, though not totally off base, they claim that Apple switched all the marketing (images, pressreleases, signage, etc) just before MWSF to spite them. True or not, and I would guess not, its still quite small of them, and does nothing to further their reputation as people in-the-know.
So techincally they were wrong, and we have only their word that it was switched on them after they reported on it. Pretty tenuous to base a claim that they were right on, is it not?
