I would agree, that if Apple had somehow managed to obtain a monopolistic position in mobile, such that people didn't have any real alternative to their platform, and they had to chose iOS if they wanted a smart phone, that it might be reasonable to put some restrictions on what they enforced people to do with their ecosystem. With monopoly market power, comes greater responsibilities (at least in the United States - but similar legal theories exist in other countries).
But, I think we can all agree, that Apple does not have a monopoly on the mobile platform, and, there is in fact at least one reasonable alternative (Android) - Some might go so far as to suggest that Microsoft's "Windows Phone" platform, and, for that matter, even Blackberry could be considered reasonable alternatives to the iOS platform.
And, regardless, 5.6 is pretty clear, ""Apps cannot use Push Notifications to send advertising, promotions, or direct marketing of any kind."" - If anything, Apple has simply failed to chase down all of the other apps that are doing this.
