Git is a source code management system designed by Linus Torvalds for implementation on the Linux kernel in 2005. The primary use of Git is as a distributed version control system for software development projects.
The creator himself has an answer for this question.
src code‘s Git Service
src code offers a simple git service for standard users. I take the latest
stable version of Gogs, apply src code specific patches,
rebase to a
prod (production) branch, and serve the application. In the last
bit’s of Linus’s famous Google talk, he mentions the issues of trust and
security with respect to git. If you watch this bit of the video, you may
understand why having a git service that is not controlled by the government or
a large coorporation is important. I do my best to protect your freedoms,
privacy, and source code.
