SpaceX is a supplier to the US government. That is not the same thing a subsidy. They're actually saving them money.
Tesla is a recipient of government subsidy, but you pretty much have to operate in the auto market. Everybody else (big auto companies, big oil) are the recipients of massive subsidies too.
True, subsidized means a portion of the cost is absorbed by other party. SpaceX provides a service the customer needs at a competitive market rate. It is not much different from how Lockheed-Martin operates.
