"Through the fall-out from the Unity decision, and now the
fall-out from the packaging of Banshee on Natty, I have repeatedly
read Canonical & Ubuntu people say "We offered our help to
GNOME, and they didn't want it".
"For starters, some people in the GNOME community moan about how
Ubuntu doesn't pull its weight upstream.They then make it difficult
for Ubuntu-y folks to contribute things upstream."
