What lock do you have on your door? Something standard like this: http://goo.gl/cuIenh (Image of lock)? That can be opened easily in a number of seconds without damaging the lock with at least 2 well known techniques. Yet that is the lock installed on new doors on peoples homes. They don't care, people don't want/need actual security they just want to keep the idiot burglars out and be able to claim the value of their losses via insurance. While professionals will get in just fine via the front door without any trace of breaking and entering. And because the people don't care, the lock-makers don't care. The ones who care the most are the professional burglars who would like nothing more than for everyone to stay asleep and preferrably for the techniques to be forgotten.
In short; lock-makers continue to make exploitable locks just fine, because they sell just fine. The moment they stop selling is the moment they'll fix the issues. Nobody is going to skip the next iPhone because the FBI allegedly managed to crack one, security is not one of the features people care about (in general).
