No, this is not what Apple wants. They make (practically) no money from people buying more apps.

It’s just a bad user experience they haven’t fixed (hopefully yet). Apple’s main goal is and will always be selling more devices. That’s how they make money. If they do sell more devices (as was the case here) it is not in their best interest to make you jump through hoops.

You fail to understand at a fundamental level what kind of company Apple is.

(By the way, this is not what Apple wants for the simple reason that you already don’t have to repurchase anything. You can put apps on any and all devices you control, the problem is just that you have to transfer them using iTunes – and that’s a train-wreck Apple seems to be unaware of. But it is possible.)

I'm sure that's correct, but in this case OP is mistaken. He failed to setup those new iPods correctly - You can use different account for iMessage, Mail and App Store. He must enter his own account in the App Store section of those new Touches and leave iMessage and Main empty (or, create new account for his/her children).

Now, those kids can't see his/her Mail and iMessages, and even if try to buy something from the App Store they can't (they need the parent's password).
