pretty sure it is against ToS for ChatGPT, Claude and Gemini.
ToS didn't stop the companies that built those models and it won't stop the companies that bootstrap off them. Until an AI company eats a multi billion dollar lawsuit for unlawful data use they will continue to operate this way.
It's against my ToS for ChatGPT, Claude, and Gemini to train their models on my writing, but they've all done that. They are free to pound sand.
Not the heckin' ToS!
Did OpenAI observe any ToS when scraping content from the Internet? Sorry, but you cannot complain about stealing the stolen. OpenAI cannot even have the copyright on ChatGPT output, because it's a tool.
