Yes. That's the biggest benefit, and another reason I'm buying it (on top of great performance for my NLE apps). I want the Mac to be it's own platform, and be under Apple's control and vision. If it's also made foul-proof and air-tight, so much the better.
I don't want another lowest common denominator OS converging on the same point.
If I didn't want platform control I'd buy some OEM device...
That doesn't mean I approve of any and every restriction. But I'm ok with a "walled garden" -- better than an open garden full of junkies and garbage. Some of the best Japanese gardens and so on I've seen had walls around them...
Of course an open garden that's beautifully maintained, respected by those in it, etc, would be even better, but that's hardly the case in real life, so that's where curation and walls come in.
To me this brings me to the Amiga and Atari and Acorn and other alternative platforms of my youth. I don't want everything to be amd64 and Windows or the nth Linux distro.
In any case, Apple doesn't force anyone's hand, if anything they make it more difficult to buy their stuff (more expensive, targeting the expensive end of the market, only 10% market share at best, different OS and now different CPU than the rest of the market, etc).
