This is the whole question.

With copyright laws, not explicitly granted means forbidden, unless covered/overridden by law (like fair use for instance). So this could be an argument against AI use without attribution / copyleft, since it's not explicitly granted.

Now, it remains to be seen if law / jurisprudence deems AI use exempt from copyright restrictions (or something like fair use applies).
