That would imply the author cares enough about privacy / security to use VPN to hide for example POP3, but not enough to immediately drop an email provider which uses unencrypted POP3 service. And that's a strange argument.
Probably because a person can more trivially be taught vpn = privacy than understanding ANY of the details and be legitimately better off especially if they are doing other stupid things like using unencrypted pop3 or use the same password at random http site as they use on their bank.
