Idk about the percentages but my impression is that there is a substantial pro-unification contingent in the Taiwanese population. Not everyone sees it as a threat, to align with the CCP. Maybe this co-founder believes it's better to hedge their bets this way?
The article at least makes it look more like an issue in terms of American law rather than Taiwanese law/policy. I'm curious if a Taiwanese reader would view it as betrayal, or as just corporate fraud.
