Imagine a private company invents a piece of technology soooo good that the US government has to issue a ban.
Apple's G4 was banned for export. Although it was not a direct order from US government. They fell into an outdated bracket of computing power exports limits. They sure did use it for advertising it.

Looks like "So good the US tried to ban us" is already in the wheelhouse!
Cryptographic technology has been under various levels of export controls for decades.
