I'd be surprised if the US hasn't inherited implied contracts via common law.

No, don't quote out of context. That's ONLY if you already previously signed a contract with them, and that original contract specifically allowed them to make future updates without your permission.

With respect, you are wrong.

It's not automatic that a contract is implied, but a contract COULD be implied by action and conduct.
