That's because they don't have any other choice but to go along with it. Granted, nobody is forced to buy an iPhone in particular, but it's the same variation of a theme. SIM locking, DRM in games, DRM in video discs, DRM in some audio discs, viral IP is everywhere. That's why I referred to it as VRM (Viral Restrictions Management). None of it hasn't been broken, or bypassed in some way, not one. But companies still go ahead and use it regardless.
