I wrote 15 months ago thanking Canonical for their release of Launchpad. However, in the interim, a part of the necessary codebase was made proprietary, namely the authentication system used in the canonical instance of Launchpad hosted by Canonical. (Yes, I still insist on using canonical in the canonical way despite the company name making it confusing. :). I added this fact to my list of reasons of abandoning Ubuntu and other Canonical products.
Fortunately, I've now removed this reason from the list of reasons I switched back to Debian from Ubuntu, since Jono Bacon announced release of this code today. According to Jono, this release means that Launchpad and its dependencies are again fully Free Software. This is a step forward. And, I did promise many people at Canonical that I'd make a point about thanking them for doing Free Software releases when they do them, since I do make a point of calling them out about negative things they do.
Like any mixed proprietary/Free Software company, there is tons more to be released. I remain most concerned about UbuntuOne's server side code, but I very much hope this release today marks a bounce-back for Canonical to its roots in the 100% Free Software world.
