That sounds so wrong, anything from a user-written program, `ed`, etc to a symlink/hardlink could read the password.

Sounds wrong because it is wrong, pure unadulterated intentional B.S.; don't know why the commenter decided to yank our chains like this.

I believe there is a meme in chat rooms where trolls get unsuspecting users to reveal their passwords by convincing them that the chat replaces it with "***" and so forth. Perhaps the GP is riffing on this.
