Most American companies (regulated ones, definitely) can't dare to touch any Chinese models, though they knew that it makes perfect economic sense. Until the taboo prevails, the cartel get's their flood of profit. That's a cartel protected by regulations.
Is "taboo" the right word? "taboo" = "banned on grounds of morality or taste". Not sending data to known IP thieves, state actors, and competitors in China (or Russia or Israel) seems very rational.
A Chinese company seems more likely to produce Chinese products that don't directly compete in the US market.
While a US company can ship the product as a feature of their platform and undercut on price while making up the revenue elsewhere
Edit: I personally use US models, but I'm not naive enough to think that's any sort of real protection of IP
