Section 230, without which Hacker News wouldn’t exist.
> No provider or user of an interactive computer service shall be treated as the publisher or speaker of any information provided by another information content provider.
So either the content is user generated and their training of the model should be copyright infringement, or it's not and Section 230 does not apply and this is speech for which Open AI is responsible.
Preposterous.
If it's not plagiarism, then OpenAI is on the hook.
