One thing which bugs me about this article is he conflates "complex" with "good". As an electronic designer I spend a huge amount of effort trying to make things as simple as possible. Complexity may be required to meet certain requirements but in general keeping it simple makes things more reliable and more cost effective.
Yes I wondered whether this complexity is a factor of enterprise design: Each engineer is responsible for a subsystem, ending up with x^n pieces, whereas the counterfeit one took 1 or 2 engineers.
There are two sources of complexity in the charger:
PFC and efficient resonant converter, which is to be expected of high-quality charger.
The whole magsafe handshaking mechanism, which looks like an afterthought to solve reliability problems caused by arcing on the pins, that also got used to block counterfeiters.
