Another method of copyright laundering is doing ML learning in a country where it doesn't protected under copyright law.

Personally, I'm on a side of using copyrighted data for machine learning input source doesn't violate copyright. Statistically, learned model for generative Ai doesn't retain even 1 bit of input. It's hard to say NN model data infringe any copyright of the input source. The copyright is applied to the expression, not the process. If the generative AI produces an image that's clearly a copy of a specific Ironman image which existed before the image generation, that's copyright infringement.
