Wonder if they are using Apple branded wall chargers or third party.

While it's entirely possible that out of over a billion products Apple has sold with a lithium-ion polymer battery that they caught on camera a defective unit, I'd guess the most likely culprit is from cheap and/or counterfeit PSUs. Maybe Apple should do more to keep their devices from accepting power from questionable chargers or maybe we need regulations that prevent poorly made PSUs and cables from being at every check out counter.

No. I already debunked this last time. The circuitry (usually a power management IC) to control battery charging is inside the iPhone. The charger is just a "dumb" power supply that sends voltage to the charging circuit.

These circuits are fairly robust and can handle overvoltages several times their normal operating voltage (5V for iPhones from USB). 

I don't know if it's as simple as that. I used (once) a non-Apple charger (fake one; one that looked like an Apple one which I bought while in another city in a Chinese shop for cheap; out of town one day) and during charging the phone display reacted bizarrely to scrolls and touches. I have never experience that with a genuine Apple charger in all the years I've been charging. I'd say the likelihood it was the dodgy charger and that it was feeding the phone the incorrect amount of voltage or similar is extremely high. You didn't debunk it for me. Whatever this charger was doing it was reaching as far as how the display functions—and the phone was getting warm. I immediately removed the charger.

I experienced exactly the same issue with a fake charger.
