Also please don't use word "learning", use "creating software using copyrighted materials".
Also let's think together how can we prevent AI companies from using our work using technical measures if the law doesn't work?
The whole point of copyright is to ensure you're paid for your work. AI companies shouldn't pirate, but if they pay for your work, they should be able to use it however they please, including training an LLM on it.
If that LLM reproduces your work, then the AI company is violating copyright, but if the LLM doesn't reproduce your work, then you have not been harmed. Trying to claim harm when you haven't been due to some philosophical difference in opinion with the AI company is an abuse of the courts.
People don't view moral issues in the abstract.
A better perspective on this is the fact that human individuals have created works which megacorps are training on for free or for the price of a single book and creating models which replace individuals.
The megacorps are only partially replacing individuals now, but when the models get good enough they could replace humans entirely.
When such a future happens will you still be siding with them or with individual creators?
Those damn kind readers and libraries. Giving their single copy away when they just paid for the single.
