My theoretical answer would be that we can regulate American companies more effectively and have them be held accountable, like when Zuckerberg had to go before Congress. I doubt you'd be able to get the CEO of a large Chinese company to do that.
In reality we don't regulate them nearly as much as we can, so the end result is that FB and Tiktok both invade your privacy.
