MasterCard’s and Valve’s statements seems to point at Stripe and PayPal as the ones who folded to the pressure. These payment processors then cited MasterCard’s rules to back up their change in policy.
MasterCard now clarifying that the payment processors are over-interpreting the rules and anything legal is ok seems a very good thing here. Valve should be able to go back to Stripe and PayPal with this and say: “Hey, you’ve misunderstood the rules you are quoting; MasterCard themselves say anything legal is ok, and that is the exact policy we’ve been using!”
Copyright law is more or less always formulated as limits on the rights to redistribute content, not how it is used. Hence, it isn’t a particularly strange position to take that one should be allowed to do whatever one wants with gen AI in the private confines of ones home, and it is only at the moment you start to redistribute content we have to start asking the difficult questions: what is, and what is not, a derivative work of the training data? What ethical limitations, if any, should apply when we use an algorithm to effortlessly copy “a style” that another human has spent lots of effort to develop?
