Lightning cables don't break on their own, they get broken through abuse.
I hear people while about their cables breaking; yet have owned about a dozen apple branded lightning cables and never one broke (one for every car (4), wife and I have them at work (2), each have two at home (4), and the kids each have one (2)). Never had oxidation, never had fraying, never had any issue.
I've owned about a dozen off brand ones as well; most of which failed within a month or two.
I had a friend complain about how fragile iPods were. After going over it with him, it turns out that he always throws it into his backpack with the headphones connected, then the books on top of it. What would happen is the headphone jack would break off inside. Well, when you throw books on top of it, the rotational forces on the jack because you left the headphones in will easily break the solder. I told him to remove the headphones before throwing it in the backpack.... never had a problem again.
Don't abuse your electronics. But can't blame the company, but can't blame the people either, many times they just don't know about these things.
