Bro, SpaceX sells the dishes at a loss. The Verge and other outlets have done teardowns to confirm this. And USAID says all they did was buy dishes.

If by "subsidies' you mean being the lowest bidder in competitive bidding... and therefore actually saving the government money compared to competitors in all SpaceX's contracts, that's a pretty weird definition of 'subsidy'.

Sitting back and letting China take Taiwan without defending them seems like a bad idea, but I admit that predicting what US political leaders might do in response is pretty hard.
