Gpg for file encryption is easy to use. The difficulty that people refer to is about key management that holds for any program, and email encryption, that involves setting up an email client, a plug-in, getting the other side to use encryption, etc. This didn’t scale well, because the average user wants a zero click solution. The average user (and some times those familiar with technology) hasn’t heard of Thunderbird and doesn’t want to set that up. They have a short password and use web browsers.
