My web site, my domain name, my home, my freedom. I avoid centralised services whenever I can. Besides, my git history is not very interesting, so I didn't feel the need to publish it.
Wouldn't it make sense to share this over https though?
I agree, https to serve software (libraries included) is a must, even if the source is open. (That's not to get into the debate on whether or not to use https for everything, but I am a proponent of that as well).
Since he's running his own server, it should be easy enough to add a certificate from https://letsencrypt.org/
