Unfortunately, the choice of license likely won't matter in the nearest future (if not already so). If a tech giant wants you open-source library, they will just point their agent to it and ask "to rewrite in the style of War and Peace". And more unscrupulous players won't even bother with a rewrite, as we've seen recently in the case of Cheatingdaddy/Pickle.
Is there any evidence of this happening? And any legal theory behind how it might have the intended effect? Training being fair use does not make AI a magical copyright-removal box.
