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.
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.
I always think about this when using a free online prettifier, decoder, and the like. But I'm sure people use those things with code/secrets from work without really considering it, and I think those habits will carry right over to AI chat.
FYI, prettier.io is open source and can be self-hosted. Also if you watch the website’s network traffic, you won’t see it uploading anything to a server: it’s all done client-side.
