"Mac mini is not an option, don’t even look at it."
Absent any discussion, I'd be inclined to ask why. The Mini certainly won't win any bang-for-the-buck awards, but compared to the $3500 27" iMac he eventually recommends, it gives up a discrete GPU, 2 CPU cores and virtually nothing else, while saving a good chunk of money, plus the ickiness of having to junk a perfectly good 5K display when the iMac eventually fails.
IIRC the 2019 report from HCSEC outlined the same bugs had yet to be fixed. I think Huawei doesn't want to fix bugs in products they aren't currently selling (in part based on Nortel code that has been patched over the last decade with new features), thus the lies and lack of investment.
