Yes. "Blame the user" is not an acceptable approach to resolving a problem with even a slight incidence rate. "We don't see that behavior often enough to commit resources to addressing it" is valid, but "they're touching it wrong" isn't when you're making a mass-produced consumer-grade product, especially a product that's meant to be carried to and fro (Apple had to learn this with the iPhone 4 too).
Some people may take pride in carrying their chargers around on special hand pillows to ensure that they are kept pristine over the years, but I personally want my products to work without demanding special accommodation for themselves. I went through 3 chargers in the 4 years I used a MacBook Pro. I didn't mistreat the stuff, I just didn't pamper it.
The answer in this case is pretty obvious, though; Apple knows that an $85 power cable isn't going to cost them any meaningful quantity of customers, and actually the breakage tends to net them $85 extra per year, so they kind of like it. There is no incentive for them to un-plan the planned obsolescence of the charger.
