This is of course only your opinion. If you can tolerate encryption without authentication, it is good for you, but no good for me. I don't care if I talk to someone secretly so no-one hears if I don't know whom do I talk to. The examples of failures you mention are really because of you reluctance to use the provided interfaces. Security -online or offline- requires to follow some protocols. If you don't want to follow them, don't expect security.
