Yeah what's curious to me is why OpenAI has grounds here vs [the abused 3rd parties]. Maybe they are trying to stand up for the people using their API as a courtesy because they want them to stay in business or something, but it seems the damaged parties are the 3rd party services bankrolling the access, and so they'd need to pursue legal action and/or patch their services.

I do imagine OpenAI has something in their terms where you're not allowed to use their APIs unless you agree to their terms, which includes payment and not using other accounts than your own (fraud). So maybe that's it?
