So all 12 people in the world who know how to read, modify and install and OS can run their paranoid versions of iOS?
In this case, you or me might be the expert, who can provide solutions for other people such as an "installer" to do whatever.
I personally don't really have a problem with Apple's plan here by the way; I think the way they're doing it is actually quite balanced and reasonable. But other people should be free to make a different personal decision on this. What I would like is to modify some other aspects of my iPhone though, like some things on the keyboard that still bug me after several years.
