So first of all, you shouldn't involve yourself in your friend's business. Fraud is generally frowned upon.
But secondly, you know that ChatGPT was trained on the entire internet, right? Like, every book. I don't think "more books" is gonna help.
I hope you take your computer skills and make something of yourself. Try not to get any more involved in this scheme, seriously. You don't need this crap marring your reputation.
Besides, there are better reasons/ways to fight the system than helping other people avoid learning.
