When was the last time you downloaded source code?

Seriously. Take a look at the applications you currently have running – your web browsers, office suites, terminals, graphics editors and the like. Have you ever downloaded the source code for any of them, made a change and recompiled? (Okay, all of you Linux-From-Scratch and Gentoo-ers can put your hands down.)

Firefox, Chromium, LibreOffice... all of them have source readily available. Yet I have never downloaded the code for any of them. If LibreOffice went closed source tomorrow... would I stop using it?
