And I'm going to stop responding to you after this. Your experiences are not universal.
Yes, any lock of any sort complicates a situation. That doesn't mean it's not a good idea to have a handle lock and a deadbolt on your front door, even if it means taking an extra second to get out of the house in case of fire. There are far more drunks trying to get into the wrong house than there are housefires. And yes, there are people who should not be using a specific type of lock and often use it anyway, and have to resort to whatever is equivalent to bolt cutters, hacksaws and drills and boroscopes. Thus do tech support people and locksmiths stay gainfully employed.
I agree that I would like to put every single person through a computers 101 class, required when they buy their first product more complicated than a transistor radio and with an annual refresher. Just for selfish reasons -- I am sick of being family tech support. But that's not going to happen. Does that mean people shouldn't have access to communications products, and shouldn't be able to use them safely? NO. Does it mean people like you and me get to do more complicated tech support? Yes.
Dude, you're getting paid to do it. Yeah, it's the same thing over and over again, so you're getting good at it. That feedback improves the process, and dealing with inadvertent locks is getting easier than it used to be.
So... it's a lock. It's a second lock. It's a second lock that protects against a very specific and far too common threat, and it's a lock that may stay locked unintentionally. Is it perfect? Nope. Neither are U locks or deadbolts. Doesn't mean I'm taking my deadbolt off or leaving my U at home.
In all of security, there is a balance between convenience and security.
