Where are the people now who claimed that LLM chats are really private and not monitored?

Every single lie of yours is exposed in the past few months.

Personally, I’ve never seen anyone claim this. At least anyone who one would think is informed on these matters.

I haven't seen anybody claiming this for consumer/free accounts anywhere.

You get privacy if you're a big corporation that needs to make sure OpenAI/Google/Anthropic can't read your trade secrets etc.

But those contractual privacy protections have been in place for a long time. It doesn't have anything to do with AI, it's been the same with Office365, Google Docs, etc.

Who claimed this? I've never seen that claim.

No sane person claimed this.

Uhm, those people never existed? Or maybe you just have very interesting friends?

LocalLLM enthusiasts exist for a good reason.
