We had a pretty good idea what Google and its AdMob division would think of Apple's new rules on outside advertising companies collecting analytics, but AdMob CEO Omar Hamoui has now spelled it out himself. In a post on the company's blog today, Hamoui says flat out that if the changes are enforced as written, they would "prohibit app developers from using AdMob and Google's advertising solutions on the iPhone." That, he says, would "not [be] in the best interests of users or developers," noting that "in the history of technology and innovation, it's clear that competition delivers the best outcome," and that "artificial barriers to competition hurt users and developers and, in the long run, stall technological progress." As for what Google and AdMob are going to do about it, Hamoui would only say that they're going to be "speaking to Apple to express our concerns about the impact of these terms." We've also reached out to Greystripe for comment -- which would also seem to be affected by the new rules -- but have yet to hear back.

Update: We just got a statement from Adobe's partner Greystripe, which says Apple's new rules won't prevent it from operating on the iPhone and iPad.
"We are pleased that Apple's new terms and conditions explicitly allow Greystripe, an independent ad network, to operate on the iPhone and iPad platforms. It confirms the value of 3rd party ad networks in enabling developers to earn great revenue with their applications."
