An interesting perspective, makes it surprisingly fair play and totally crippling to third parties at the same time.
I guess the outcome will be that outside some completely irrelevant oddballs there will just be one or two entities like Epic serving the intersection of non-casual gamers and people who consider the iPhone a gaming platform and they won't pull much market away from Apple, but serve as a limiter to how much Apple can abuse their platform rule. It will look like a failure, but only because some of the limiting effect on platform abuse will also bleed into makets not directly affected by EU rules.
