In the case of Fizzy, the app that 37signals has made “source available”, the real motivation for publishing is form of advertising for Ruby on Rails.

DHH is on a mission to show that you can write great software with way less bullshit than is in vogue.

This code base is sparkling in its design. No build frontend, server side rendered templates, minimal js used primarily to drive interactivity, extremely simple models, jobs, and controllers.

It has < 3000 lines of js with incredibly rich interaction design, when was the last time you saw that?
