I know it can be frustrating to have a software not work as expected but, I don't think Ubuntu is doing too bad in this respect (I have been using Kubuntu @ work and Fedora at home for the past 2-3 years). The author IMO is a bit too harsh on Ubuntu. On a somewhat related note, I think people should also read this while passing judgement on another OSS (esp bug fixes):
