If the market wanted parents to be able to figure this out it would be getting it right. It's obviously a dark pattern that benefits everyone but the parents and their children. If more people stopped to think deeper about this they would and should be very disturbed by what this means.
The devil is in the details though, there are some subtle features that need to be incorporated into the mechanics for the sputnik to work right. I have built a sputnik from scratch before, only after talking to Oli Diederichsen at a LockCon did I get some additional clues.
Also, I think there are plenty of other interesting things one could do besides brute forcing the lock with a simpler tool. Falle Safe has a single-wire variant on this for decoding locks. Again, the devil is in the details, just ramming wire up a pin stack doesn't get the job done.
