Why don't we have a Steemit variety of Github yet? (for developing open source software)

I can't believe we don't have an open-source platform that pays money. We have

• Social media
• Decentralized Youtube
• Decentralized Freelance Marketplace

Okay, as I was writing this blog post, I ran across this post https://steemit.com/steem/@someguy123/git-steem-decentralized-github-using-steem

Apparently, some others have put quite a bit of thought into it. However, it's not made yet. I tried googling it and all I could find was a bunch of blog posts.

I really hope github via steemit becomes a thing.
