One thing that puzzles me is how he coined CADT to describe the Gnome development process, while also having embraced OSX as some kind of example of good computing. Because Apple have been just as much about "churn" and dropping of old code for new code, afaik.

Heh, and while writing this it dawns on me that it may well be that he is about OSX because UNIX. Meaning that OSX is a BSD derivative, that in turn is derived from the historical UNIX. While on the other hand Linux is just a bastard clone.

Because it hit me that i have seen some similar fervent anti-Linux sentiment from other UNIX people, related to either the BSDs or Solaris.
