The case of POP3 and STARTTLS vs POP3S is different, because practically all POP3 providers these days require encryption before the e-mail client is allowed to transact. It's the same encryption method/protocol and the same requirement, it's just that POP3S goes straight for the TLS handshake while STARTTLS (with the security concerns detailed in the article) begins talking on an unencrypted channel before getting on with the mandatory handshake.
