Modern semiconductors seems a lot like the F-1 engine on the Saturn V. Even if you had the blueprints for it, you couldn't build it without doing a lot of work to rediscover all of the missing details that were in the minds of the engineers and tradesmen who built it. Also, (I didn't read the original article), but there's been some suggestion that some of these companies, like HSMC, were really just investor scams. They raised a whole bunch of money, promised a lot, but didn't actually know how to do what they said they did. Kinda like a Chinese Silicon version of Theranos. I think HSMC even had an ASML EUV machine, but never got to use it.
