Open-Source ScratchR2!

As you may know, Scratch Team members claimed at multiple time that Scratch is 100% opensource.
It's not totally right. What is opensource is scratch-www, the frontend of the website. It's basically what you see on scratch, the buttons, the pages, etc, and only on Scratch 3.0-style pages.
But ScratchR2, the thing behind that, isn't opensource. It's all the system used for database, the API, the admin consoles, etc.
To fully reach Scratch's goal of being a 100% open source platform, we WANT, as the community, that ScratchR2 become opensource, too.
