Legal arguments are just social and economic interests in disguise. Some are obvious, some harder to spot.
One of the most devious legal tricks I read recently is this:
GDPR gives people the right to have illegally used training data removed. This would in many cases require the model to be trained again - without that data. BUT as training LLMs is such an obscene waste of resources the right to erasure is overridden by the public interest of mitigating climate change.
I mean. Wow. Just wow.
