There was "immense value" in every monopolist that was rightfully broken up or restricted. There's "immense value" in every monopoly / duopoly market. So what. The richest company in the world is swimming in money, pays little taxes, and gouges every developer who made its products successful. They are nothing without the developers, they're simply in a good position to abuse them, a position that they carefully crafted for themselves.
On top of that, we really don't want to be in a situation where every large software producer has to create their own phone to maximize their income. It would be a terrible waste of resources. What Apple wants to own can't be owned.
