These is exactly what my first thought was! Installing open-ssh and git is kind of my first activity on a new computer.
But I believe they are talking about setting up a git server. The thing that we rely on GitHub/GitLab/Bitbucket for. Richard counts them as an added dependency.
(I mean, he is not wrong in being worried about that. You are basically giving your all your code to a company. Which does not matter for open-source projects like SQLite, but it does for many private projects with code as their primary IP)
What is a “git server”? There’s no distinction between client and server in git; you can “git pull” from any machine with the normal “git” program installed that you have SSH access to.
Who uses git-daemon these days? When's the last time you saw git:// in a README?
Practically all use of git is either the "smart HTTP" protocol over HTTPS, or over SSH. git-daemon is plaintext, you wouldn't want to push over that, and for public use HTTPS has won.
I believe grandparent means what is these days called "forges", a web frontend with user accounts and such, with an extra heaping pile of features.
