Well, surprise surprise -- Apple's ever-expanding content control freakishness is also about Google (move over Adobe!), as Apple has now implemented new rules that prevent developers from sharing iPad and iPhone usage data with many third party ad networks -- including Google's AdMob ad network for mobile devices. What does that mean? It means that Apple's new iAds mobile ad network will trump most others for iPad and iPhone users.
The Apple v. Google knock-down cage match continues ...
(and, isn't it interesting that Microsoft is nowhere to be found these days in any of these conversations?)
