The thing is, what you are describing is arguably theft. It is purposefully circumventing the license and restrictions chosen by the author, in order to steal their code, so that it can be sold and used for profit. This is along the same lines of why book authors and artists have been suing AI companies.

Another point, there is a lot of free and permissive license content to train AI on, where the GPL or copyright can be respected. In many cases, the violating AI companies knew what they were doing was wrong.
