What information exactly is misleading?
The most disturbing thing in the report is how he points out that ASML PhD's have double the salary and much better benefits than SMEE's PhD's, and this is based on public job sites and comments on job boards, not the Equal Ocean Report. This could be solved if the Chinese government injected capital into SMEE or allowed SMEE to IPO to attract private capital. Since this seems so easy to solve, I don't see why it hasn't been done already. The most critical part of the semiconductor race will be human capital.
The second disturbing thing is that he claims that China's 90nm SMEE 600/2 machine from years ago is not "selling in relevant quantities." While this may be changing due to US export bans, it would be nice to see some concrete proof that sales of the machine and increasing and that it is being used by customers in volume. He also claims that this is a specialized machine for backend lithography. He does seem to think SMEE has developed a working prototype of a 28nm ArFi machine, but thinks that volume production will not be online until Beijing GuoWang's new plant is completed in 2023, followed by a year of integration which takes us to 2024. And even then, the product may not be commercially viable. In terms of commercially viable front end machines, he sees SMEE as "at least" 20 years behind ASML. Basically, China is able to prototype reasonably (only ~10 years behind) but the quality of its products are low so it never achieves commercialization. However, I still think this is due to the human capital issue mentioned in paragraph #1.
I think if we consider Chinese semiconductor watching to be similar to PLA watching that we are all familiar with, then I think there is a degree of natural skepticism from English language sources who do not have intimate understanding of the Chinese language rumour base and who have done the legwork to correlate them.
I do think that relative to PLA watching, Chinese semiconductor watching is in a bit of an earlier state of maturity with a lower barrier to entry yet also with more useful information openly available... but PLA watching and the quality of "PLA analysis" or news on the PLA that most English language news media, defense journalism, and content creators put out, provides a useful starting point to treat those same analyses on Chinese semiconductors with a similar degree of skepticism.
At least, until we have a more robust system in place.
