Quite the opposite actually. My intent is to shed light on the fact that sharing information with OpenAI is not private. And you should not do that with information that you wouldn't even share with people you trust.
I'm not OP, but I think you're missing the point.
Privacy and trust isn't really a 1D gradient, it's probably planar or even spatial if anything.
Personally I'd be more willing to trust OpenAI with certain conversations because the blowback if it leaves their control is different than if I have that same conversation with my best friend and it leaves my best friend's control. The same premise underlies how patients can choose who to disclose their own health matters to, or choose who their providers can disclose to.
Same reason behind why someone may be willing to post a relationship situation to r/relationship_advice and yet not talk about the same thing with family and friends.
I ask that you consider the people who use Reddit and the people who run Reddit independently. The people who use Reddit are not in a position of power over someone who asks for advice. The people who run Reddit on the other hand, are in a position of power to be able to emotionally manipulate the person who asked for advice. They can show you emotionally manipulative posts to keep your attention for longer. They can promote your post among people who are likely to respond in ways that keep you coming back.
OpenAI has a similar position of power. That's why you shouldn't trust people at either of those companies with your private thoughts.
