How are Apple preventing you from buying the ever more popular Android phones? Or Web OS phones? You, a member of the market, buy the phone with the features you want. If you don't like Apple products, or the app store they provide, buy one of the many hundreds of alternative smartphones, many of which have large adoption.
"How are Apple preventing you from buying the ever more popular Android phones?"
They aren't and I have. Right now, however, the biggest momentum that the iP(hone|ad) has is the app market, and the fact that a lot of large organizations have special support for its walled garden. 3.3.1 is Apple's way of trying to ensure that it is a specially cultivated walled garden, and that it's more likely that "there's an app for that" only applies to the Apple devices.
I think it's a futile move that is too late, but that is the clearly obvious motive behind 3.3.1. It is anti-competitive and without justification, and honestly it's a bit bizarre that so many fail to grasp that.
