Upon reading the title I wondered "would anyone ever create a VPN client that doesn't use encryption?" and thought, with the "2k lines" as additional evidence, that it was the source code which was somehow encrypted/obfuscated to e.g. prevent censorship...

I was also expecting to see a single file at that line count, but then again I'm not really familiar with Go. Is this style of "many tiny files in multiple nested directories" common/expected for Go? I know it's rather common in many other languages, but also not what I expect when I see "Simple" or explicit mention of a low line count.
