The FBI was accused of violating copyright regulations by using OpenZeppelin's open source code base in smart contracts without including MIT license annotations. The accusation was made by X user 0xCygaar, pointing out that the smart contract deployed by the FBI on the Ethereum network was marked as "unauthorized", which may involve infringing the terms of the MIT license. Although publicly suing the FBI faces challenges to sovereign immunity, external pressure may prompt the FBI to amend the contract to comply with open source requirements. (Cointelegraph)
