I don't get the sense that Elon's companies care much for the contracts they sign.

I wouldn't trust a contract from one of Elon's companies unless they were willing to put in escrow an amount that would make me whole in case of a breach on their side. (And that amount would be quite large in the case of a potential breach involving using prompt data for training.)
