Apple and Google gets to act as middle men because their app store provides value to the end user.
Users are free to use the mobile browser on their phones but most of the time native apps are a better experience. And guess who develops the framework and tools to create these value-adding native apps.
But there's not an anti-trust situation with app stores: Apple, Microsoft and Google all maintain their own app stores. No, they don't let anyone else operate an app store on their mobile platform, but other companies are free to create their own mobile platforms if they don't like that. Apple and Google aren't doing anything illegal to stop other mobile platforms from existing; it's just that users really don't want another platform right now.
>But there's not an anti-trust situation with app stores
I am not saying that there are current or even future anti-trust issues with app stores. I was simply using that analogy to illustrate that the "free market" can move in a direction that is less free to an extent that is negative for consumers. This can happen because consumers are free to choose.
In other words, that anti-trust laws exist and have been employed to combat this is simply offered as evidence that the great-grandparent post above overlooks the fact that the free market can lead to reduced choice for consumers.

This is the free market at work.
