Just as with SELinux or AppArmor, you can ignore it if you think your normal practices keep you safe. That's probably mistaken but it's fully under your control:
I don't mind those features in and of themselves, and I see their value; it's Apple's paternalistic attitude that bothers me. I've used Macs for my entire life and always felt I still had a semblance of control over the hardware and software that I bought, but that feeling of control is going away.
Yes, iOS is a better example. I'm not a big fan of closed platforms in general. I like to be able to decide which software I run on my device, so my most recent laptop and phone purchases have been GNU/Linux devices.
I understand and appreciate the security advantage that comes with protecting users from themselves, but at least SELinux and related software still give users the rope needed to hang themselves if they're into that sort of thing.
