> You agree you will not use, or allow others to use, Meta Llama 3 to: <list of bad things>...
That terminates your Llama 3 license forcing you to delete all the "materials" from your system.
Or, it means you have broken a contract (of adhesion) formed by acquiring the weights from Meta. You can break contracts! Meta could take a civil case against you, but that's it. The AUP is a document, it's not going to force you to do anything. The court could potentially force you, but that's unlikely, even in the more unlikely event that anyone cares enough to find out what's happening and bring a case against you.
