I think that this analogy is generally not a good one: commercial players do not have vetted interest in being copyright absolutists, on the contrary: commercial players do what's in the best interest of their shareholders, normally profits. If there is low commercial risk in doing something, and some commercial gains, that's what should be done, modulo bugs in implementation and changing external factors. This motivation better explains many actions related to software licensing better than any legal theory. Another example is the practice to drop copyright years from copyright notices. Some commercial players do this because they save developer time, and believe that the likelyhood that a copyright claim will have commercial effects depending on the presence or lack of the copyright year is low. This is more true if you are a large commercial player: then you can use other arguments to win your case, even if the other side would have a valid argument in a missing copyright year. The copyright absolutist approach would be to look at laws and prior cases and recommend what is the safest and most conservative approach. As far as I know, that is still to do increment copyright years. Comparing the situation to LLM outputs here, commercial players have a vetted interest in being able to offer LLM products, and that depends on good models (trained on good inputs) being legally distributable. So they make the legal idemnity promise to be able to end up in court with copyright holders and take the fight there, and assumes that they will reach a commercially beneficial deal in the end. I don't think they reason that they necessarily have the legal right to do what they do, that's not particulary relevant for making commercial decisions. /Simon
