I don't understand what your argument is. Untethered jailbreaks on iOS are worth gigantic amounts of money because they are not easy to come by.

But they have existed for every version of iOS none the less. The relative difficulty may quite well be due to other reasons - closed source, locked down hardware etc. Says nothing about software security.

Rooting your phone when your not allowed is so common in android it might as well be a non-event.
