Check the parent article that explains it well. Apple didn’t defy common comp arch wisdom... they applied it.
The reason why is hard for Intel/AMD to do the same is not the lack of engineering geniuses (I’m sure they have plenty), but the support for a legacy ISA, and a particular business model.
What Apple defies is common business survival instincts: why spent so much in RD of a chip if there are market leaders that are impossible to beat? The answer seems to be obvious now... but probably it wasn’t obvious when Apple acquired PA Semi in 2008.

Having own silicon, means the upstream will not be able to turn lights on you (Samsung — a company keeping a quarter of its host country's GDP hostage.) I believe the immediate goal of PA Semi purchase was that.

PA Semi was clearly a diamond in the rough. It took a great insight to single out PA Semi, because on the surface it was a very barebones SoC sweatshop, but in reality PA were the last of Mohicans of US chip design.
PA was a place where all non-Intel IC engineers left to after the severe carnage of microchip businesses of US tech giants like Sun, IBM, HP, DEC, SGI..., and etc.
It was a star team which back then was toiling at router box SoCs.
