Because perfect security is impossible and you only have to leak your real IP once - especially with committing to github it would be so easy for a tool or plugin to leak that.

Tor browser for accessing the website. For commits a git+SSH config using Tor's socks proxy port will fail closed.
For other tools/plugins that you can't be certain about you would have to run things in a VM that prevents non-Tor connections - e.g. this is how Qubes/Whonix does things.
