Bad analogy alert
Try this
You buy a Ford which is widely know for it's flawed security and thefts are common and widespread. To alleviate this you buy an Acme Alarm(tm) in attempt to keep the thieves at bay.
Unfortunately, the Acme alarm is also a piece of crap and eventually it fails spectacularly causing you to be locked out of your vehicle completely.
Who is to blame;
A) Ford, for making a vehicle with such poor security fundamentals.
B) Acme, for making a low quality security product
C) You, for buying a car with known security flaws
D) all of the above.
