Why this project is not on for ex. GitHub?
Many in the free software movement shun commercial software. To make things worse, GitHub recently got aquired by one of free softwares old enemies.
Personally I've used and even recommended GitHub before Gitlab became available and I don't shun them or even Microsoft, but I also see where they might be coming from.
If you could introduce a single point of failure merely by using git with a proprietary remote service, then you are using git wrong.
