I think it matters. I do think the technology is interesting and useful, but if you create something using AI models based on license violations then what stops someone from taking it? What standing would you have in court to say that it’s yours? Why is the AI model “fair use” but a thing made with it is proprietary? These are things yet to be fully determined, but given that training and running AI is not cheap these companies are building on sand IMO.

Well who creates the keys and who stores them? That’s all you need to have a back door.
