You cannot hash passwords in a password manager. It has to be reversibly encrypted and turned back into plain text before utilisation.
So when people complain about password managers storing plain text (as opposed to hashing) they're barking up the wrong tree, it is a necessary evil.
You just want to see them encrypt those plain text passwords so that offline recovery is harder. That's what both Firefox's master password, CryptProtectData() for Chrome/IE, and the key-chain in OS X provide.
Ah come on, you obviously understand what he is trying to say. You don't always have to interpret every comment online as if the person writing them is stupid.
I'm not sure this is what you mean to say, because, obviously, good password managers don't store passwords in cleartext.
