Would that matter if the company wants to do business in countries with more restrictive laws? I.E. if I wrote my own spin-off of a popular book series, which was somehow considered fair use in country A, but considered infringing in country B, the publisher could get it removed from stores in country B. By the same logic, if AI training is ruled as copyright infringement in the US, it won't matter if the company trains their model somewhere else - if they open a US division to sell service using that model, they'd get sued. Granted I'm not an IP lawyer and AI IP law is in its infancy - maybe I'm missing something?
