Legality is a concept that exists only under a jurisdiction of a government. Blockchains are supposed to be sovereign, code-is-law, free from governmental meddling. So by the spirit of the blockchain concept and smart contracts, it couldn't be illegal, nothing can. Everything happened exactly to the letter of the contract, and there's no judge to disagree. Of course there's recurring theme of crypto users shouting "fuck governments, we're censorship-resistant!" on the way up, and "that was illegal, I'm calling the FBI!" on the way down.
