All browsers should care about security. All browsers can have vulnerabilities. It's not an excuse to ban competing browsers if users want to install them. That's the essence of the matter. Apple's behavior is anti-competitive in doing it. In fact, I'd argue that it reduces security, since users can't install more secure browsers than Apple's own one (and no one would care to even make one since it won't be usable).
