So while I didn’t quite follow that reference, it’s true that if Trump were to ban them for simply being owned by China, then he’d be kind of screwed because he’d then have to ban all his own merch like the Trump phone and his made-in-China MAGA hats.
(Though I thought that anybody as smart as you think you are would've inferred that without issue)
