The regulation was originally an antitrust case leveled against Apple by the European Commission. It contained many things that are unrelated to saving human lives, but will make developers and users lives better in the long run. We do this because the status quo (Apple having unfettered control over their ecosystem) hasn't worked out for people outside of the ecosystem. In lieu of trusting the world's largest company to build a text-messaging replacement that works on other phones, we do have to drop the life-saving legislation to focus on nannying the next iPhone.
