Ah there it is, the obligatory blaming of the user. It's a well known fact that Apple makes cables with insufficient strain relief[0]; it's infuriating when somebody starts pretending that isn't the case. Cables aren't fruit, they aren't meant to "go bad". Even a cable that gets replaced for free is still a cable that gave me grief and wasted my time.
Even your claimed failure rate, 2 replacements in 10 years, is abysmal! That's what, 3 or 4 years per cable? I have cables 20+ years old that are as good as the day I bought them.
I think two have gone bad, both replaced by Apple care.
