Good idea. Let’s make it a minefield of copyright infringement for the user so they never know whether it’s emitting something novel or it’s emitting AGPL code.
That's what the legal department at my employer (huge multinational corp) came up with: When an employee uses one of the approved gen-ai models it's on the employee to check the output isn't infringing - legal argues that not doing so would be grossly negligent, making the employee personally liable.
