I think we are at a looking where we just have to let go unless we are Disney, with an army of lawyers. May be it's time for the change in thinking. Having said that. Attribution allows a person to trace the source, it's not a success marker anymore. Probably, if enough negative statements generated by AI get popular, that could potentially piss of countries/people for example some LLM recognizing Taiwan as independent country you can bet China will push for attribution to sources. We have bills pending in multiple countries that want access to personal of encrypted messages to trace the source.
