1) Never blindly trust the opinion of the head of one group when they criticise the opposition. They might be right, but they have reason to misrepresent the details, and as they say, the devil is in the details.
2) Also kind of misses the point and tries to impose the Western consumer model (which, to be honest is kind of insane) on other cultures. We obsess with constantly improving specs, more power and more stuff when in reality, for most of us, a five your old computer more than handles our needs.
The problem is that vendors can't survive on buy once every five years and so they market heavily to get you to upgrade using FOMO and fear of obsolesce - and even doing things like dropping support for devices after a couple of years or implementing features that can only work on the newest device to force you to upgrade (see: Apple's 'upgrade every year' mindset).
3) There are 1.2 BILLION potential customers for Chinese chip makers in China. That's 2.5x the entire US market. Many of them are just getting their first ever computer, tablet, phone or smart watch. Do you really think the fact that it's not 4nm tech really matters to them?
That's probably good enough for military equipment like missiles.
Also the more they get sanctioned it becomes a self-fulfilling prophecy. They'll cut off revenue to companies like ASML which will slow down their funding and eventually we will arrive at a point in the century where things will start to look inconvenient for many stakeholders.
Despite recent advances, ASML CEO highlights China's significant technological gap in semiconductor manufacturing. Chinese firms face major hurdles without access to crucial EUV technology, even as they represent nearly half of ASML's current sales amid growing geopolitical tensions.
