Firefox only exists because Google needs an alternative to pretend its not a part of a duopoly. That alternative doesn't have to be Firefox tbh. They could stop sponsoring and choose any of the thousands of alternatives. Similarly Safari exists because Apple has exclusive control of what goes in iPhones. If it is ever forced by legislation to open it up to other browsers, it will lose some of that control. I don't think it will ever be forced to fully open though. I expect apple to make it so only a select number of entities can afford to release a true Safari competitor.
