UX can guide the user toward what it thinks to be the best option, or it can forbid the user from choosing anything else.

The former helps grandma get her tasks done and lets the power user go the extra mile.

The latter helps grandma get her tasks done, tells the power user he's not worth supporting and blames grandma for it.

UX can be paternalistic as well

It can also be very bad or the very opposite of what Apple does and also be the best around and still let people free to explore all the options available.

There is nothing specific in what Apple does that can be reduced to simply UX.

Maybe ergonomics is more correct to define what Apple tries to do with their human interfaces, but the Apple store or the locked down platform have nothing to do with either UX or ergonomics.

What Apple does is to remove electric plugs from the walls because someone could put a fork inside them and experience an electric shock.

And I am not the one saying it, I was answering to "Apple removed trojan and viruses to help people who don't know better".

That's paternalism.
