But ChatGPT responses are not copyrighted and cannot be copyrighted by OpenAI. They are the work of whoever asked a question, so in this case the user bypasses the protection to create its own work, not to read someone's else work.
The model is proprietary and owned by OpenAI, therefore the outputs pf a proprietary process are at minimum copyrighted by OpenAI. When you sign up, you obtain a license to use that output as prescribed by the license.
