A reason why authors SHOULDN'T sign up for ChatGPT plus accounts:
If OpenAI's billing DB leaks, and your name is in it ...
People will start questioning whether you actually wrote your books, or used a mechanical ghostwriter.
US case law denies copyright protection to AI-generated material.
Your publishing contracts typically include an assertion of sole authorship by you.
So if it looks possible that you used ChatGPT, you might end up pissing off your publisher and/or losing a book deal.
@Enby_Neala @cstross I guess that's a way for aspiring writers to use it without worrying about billing details outing them. Soon there will be ChatGPT in nearly every online service, and shady folks will likely figure out how to use it to author novels under the guise of "I just used that service to send emails" or similar.
