Surprise! The U.S. government is once again going to throw Apple under the microscope and investi alleged anti-competitive practices, this time for the new language Apple is using in section 3.3.9 of its developers agreement which appears to be directed straight at Google’s AdMob. This information comes to us by way of The Financial Times. This would mark the second time that federal regulators have looked at Apple relating to mobile ads and one of many other preliminary investigations. It was just yesterday that AdMob broke its silence on the matter and went on the offensive saying that Apple is putting up “artificial barriers to competition” which will only serve to “hurt users and developers and, in the long run, stall technological progress.” The question in this case appears to be whether or not Apple’s fiercely competitive tactics with iOS advertising are legal or warrant anti-trust action.
