Yes. And that's part of what I paid for.
Show us where Apple advertises this and I might believe you.
Apple advertised implicitly by consistently fulfilling the promise that if anything bad happens to your iPhone, in most cases an Apple Store can fix it.
Control is a part of this implicit model. This is not a model I myself like (I prefer the more freewheeling Android ecosystem); but I can appreciate why people respond well to it. To your average person who doesn't give a shit about unlocked bootloaders and just wants a way to regularly be in touch with their family and friends, the Apple model probably works better.
