To me, this is no different than Facebook charging users for features they already got for free. For example, "pay us $5/month or your feed items will always show up at the bottom of your friends lists" or "pay us $1/month or your news feed of your friends' activities will be delayed by 48 hours" or some crap like that. They'd still be giving your feature, technically, but they'd be limiting it unless you paid instead of giving you something EXTRA if you paid. In this case, they created an API for developers that brought thousands of developers and a whole lot of user traffic to their system when they didn't have a clue how to monotize it. Now, after all the work has been done by developers, they are imposing limits than can only be removed by paying instead of adding NEW VALUE to those developers who pay.
