It's not a stretch given majority of those companies are economically dependent on China as China is dependent on them, also some of their major customers are in China. That's the reason Taiwan selected KMT to forge closer ties with China during this elections. In Kaohsiung which was an impenetrable constituency for KMT, Han Kuo-yu won by a landslide based on closer economic ties with China to bring jobs as the main issue.
Taiwan and China are politically different but economically both are intertwined be it Foxconn, Asus, Quanta, Winstron, Gigabyte or TSMC etc.
So including those 10 within greater China is correct.
They are political ally of USA and economic ally of China.
It's again a minority opinion against the majority of the HN community so this comment might be downvoted as usual.
