the analogy in the anti-fair-use argument is that if I am the WSJ, and you are a reader and investor who reads my newspaper, and then you go on to make a billion dollars in profitable trades, somehow I as the publisher am entitled to some equity or compensation for your use of my journalism.
That argument is equally absurd as one where you write a program that does the same thing. Model training is not only fair use, but publishers should be grateful someone has done something of value for humanity with their collected drivelings.
