> Imagine canning your 7nm process last minute only few years before the chip shortage.
What?
The chip shortage was a shortage of cheap but inferior 28nm, 40nm, 65nm and 80nm chips that GlobalFoundries was (and still is) well positioned to profit from.
This is a good point, but they weren't necessarily very cheap or inferior; they were just fabricated in larger process nodes, which for analog chips (as many of them were) doesn't imply inferiority.
