I think your understanding of competition is a little warped or flawed. The mark of competition isn't that a company's price changed. It's that other people/companies were free to enter the market.

You are absolutely free to go and develop your own phone ecosystem and app store, or go provide your app development services elsewhere. That is competition. And that is what the court has found.

Competition is not that I need to give you more shelf space or a better price for selling something on my marketplace.
