Eh apple isn't as good with security as you think...
This is true. Lets talk about iTunes security as an example.
You know how you are limited to creating a limited number of iCloud accounts per device? Know why the iTunes store no longer accepts prepaid debit cards such as those prepaid AMEx and Visa cards at 7-11?
Well, they used to accept any of those cards and as long as you had a balance of at least two dollars and had a nice collection of those cards, you could create an iTunes account using those cards. When you create an account, Apple places a $1 hold on the card just to verify that the card is valid. You could then immediately buy up to $37 worth of videos, apps or whatever you wanted and they would immediately start downloading. Within a few minutes, iTunes would then try and charge the card and find that there was insufficient funds but by then, you already have everything downloaded.
If you had more than one iDevice or computer, you could do this all week as long as you didn't use the same card or iDevice to create an account more then twice in 7 days. This is why you had a collection of lots of those debit cards.
Apple became aware that this was going on with people after some people doing this for 5 years or more and then became very strict.
Now there is a way to bypass the activation lock for jailbroken devices on 7.0.X.
