Editor’s note: Is Apple going too far with its restrictions on developers? Alistair Goodman thinks so and explains why in this guest post. He is the CEO of 1020 Placecast, a location-based mobile advertising startup.

Apple’s recent behavior bears an increasing resemblance to carriers with respect to the walled garden they are creating around the iPhone. Restricting applications, restricting the use of location on the device, blocking Flash, and now potentially taking advertising in house—these moves are taken from the carrier’s playbook with the hope of locking out meaningful competition. Ironically, Apple may very well become the barrier to open innovation in mobile in much the same way as carriers have been before the iPhone came along.

What is clear from the announcement to developers last week about plans to deny some apps that deliver location-based advertising is that Apple intends to control the flow of marketing dollars on the iPhone. Less clear are their plans for sharing the wealth with the ecosystem—but if you look closely at acquisitions like Placebase, key hires and patent filings, what emerges is a potentially more ominous view of a company that can only compete in the direct advertising business head-to-head with Google by seizing control of location-based advertising.
