I've worked with Canvas a bunch and concluded that they really don't care about open source. Maybe they did at one point when they were the underdog and it gave them an interesting edge. But now they will provide no support to help you run it yourself. The wiki pages outlining how to deploy are community-maintained and pretty frequently out of date. They're attempting to replace pieces (analytics and quizzing) with closed-source standalone applications.

You honestly can see the difference when a company gives a crap. For example, look at SpiceWorks in the ticket software area. Their directions are clear and easy. Heck, they have VM images.
