This is interesting from the legal point of view, because AI service providers like OpenAI give you "rights" to the output produced by their systems. E.g. see the "Content" section of https://openai.com/policies/eu-terms-of-use/ https://openai.com/policies/eu-terms-of-use/ Given that output cannot be produced without input, and models have to be trained on something, one could claim the original IP owners could have a reasonable claim against people and entities who use their content without permission.
