I find the recent war of words between Linus and the GNOME developers interesting. In the first round of this war, Linus encouraged people to swicth to KDE. He later referred to GNOME developers as interface nazis.
That was six months ago. Now, after being challenged by one of the GNOME developers, he has released patches for GNOME that he says make the code more logical. I’m going to pull them, see exactly what they do and come back with a review.
