Earlier quoted context omitted.
Even though Apple hasn’t been sued for Apple Maps, they are not safe from such antitrust charges. The antitrust cases move slowly so it’s possible that they just haven’t gotten to there.
The problem isn’t that Google has search and makes Android. It’s that they have search and paid android phone makes and Apple oodles of money to make Google search the default. Apple would not need to pay anyone to make their search (or maps or browser) the default. It would be the default on Apple devices and not used much outside of that.
Would that bother Apple? Their platform is the most valuable to advertise on. They’ll make money. The question is, will it make as much as Google was paying?
