"The latest round of fighting seemed to begin when news came out
that Ubuntu had changed the affiliate code in the Banshee audio
application to direct funds from a revenue sharing agreement with
Amazon Music Store from The GNOME Foundation to Canonical, which
under the GPL Ubuntu has the right to do. But many within the Open
Source community saw this as unneighborly and provocative. After
all, Canonical is seen as a wealthy company while GNOME is a Open
Source project struggling to raise enough capital to stay afloat.
GNOME played a large part in Ubuntu's rise to Linux distribution
dominance and yet they've been given the boot lately. In fact, bad
blood between the two organizations go way back."
