This is so unbelievably wrong. Git absolutely is a data store. It just so happens that its primary use-case is version-controlled code. There's no reason why it can't be other data - even binary. Other text that isn't code is absolutely fine. Also, if it's in GitHub, it's almost certainly is using Git. Though I haven't tried this service out yet, my guess is GitHub is being used as a known central Git repo source with a reasonably well developed ecosystem and security mechanics as well as being the most widely adopted Git VCS platform on the market. But in theory you could use any Git repo on any platform (or no platform)... it sounds like it will just need to end up on GitHub currently to make use of the orchestration this service provides.
