It's still probably extemely against any reasonable business's code of conduct.
That you're getting downvoted for an obvious statement like this suggests to me a lot of HNers are disclosing trade secrets and proprietary code to OpenAI that they know damn well they shouldn't.
Why would it be? Most businesses have no issue hosting private stuff on cloud or in github private repos.
TOS and trust matter the most.
Because the business has those relationships worked out. I can't just decide that I trust OpenAI and send my company's code over, that would be insanity.
