That is a very good point. I had the chance to start my "Git adventure" with Mercurial on some in house software at my university. They then switched to Git with Gitlab. And now I use Git with Github. It helped me to realize which piece does what. But if you start with popular tutorials, everything is Github. Github even released a CLI wrapper around Git that integrates Github-specific concepts.
