Well, this sounds like a monopoly problem, not a free speech problem. If Apple were forced to allow alternative app stores this wouldn't be an issue. Note that they don't have to advertise or host these stores, merely not actively design their products and TOS to prohibit them. But then of course they'd risk losing out on some of that sweet, sweet 30% cut. I see this concern pointing not at stronger protections for speech, but stronger anti-trust enforcement.
