> There is nothing private about the internet and I wish people understood that.

I don’t know that that is useful advice for the average person. For instance, you can access your bank account via the internet, yet there are very strong privacy guarantees.

Concur that it is a safe default assumption what you say, but then you need a way for people to not now mistrust all internet services because everything is considered public.

I'm more so talking about posting things consciously on some platform, not accessing.

Well even when consciously posting on a platform, you could assume it’s stays on the platform. Sure, tech people know it’s public data by then. But for an average person, it’s not weird to think it stays on the platform. Especially since you have to log in to even see posts.

Why would anyone assume it stays on the platform? It's public now, therefore anyone can see it.

Because that’s normally how life works. Things stay within a context.

Not online, which again people should remember.
