One quasi-political issue that has somewhat more pervasive importance is the general relationship between Debian packages and the Ubuntu packages derived from them, which occasionally is a point of friction if the maintainers have different goals. In most cases it isn't a big problem though, afaict. There are reasonable number of cases where it's even the same maintainer.
In March 2006, a group of Debian maintainers started to attack the cdrtools project.
The latter attacks have been based on the fact that cdrtools was licensed under the GPL. As a result, on May 15th 2006 most projects from the cdrtools project bundle have been relicensed under CDDL (giving more freedom to users than the GPL does). At the same time, an important amount of additional code (DVD support code from Jörg Schilling and a Reed Solomon decoder from Heiko Eißfeldt) has been added to the freely published sources.
In summer 2006, the attacks from the group of Debian maintainers escalated and in September 2006, these people created something they call a fork from cdrtools. They soon added a lot of bugs and this way turned the "fork" into a questionable experiment. The last work on this "fork" has been done eight months later on May 6th 2007, then the leader of the attacks stopped his efforts on the fork and instead started to advertize for nerolinux. During the Debian project activity, the source code distributed by Debian was modified in a way that violates GPL and Copyright and makes it impossible to legally distribute this "fork" called "cdrkit". There is no license problem with the original cdrtools.
I hope all is clear now.
""" Ask your Linux distributor to include recent originals instead of broken forks.
Tell them that you like to decide yourself which program you choose. Whether it is the fork or whether it is the original program depends on which package works better.

The following Linux distributions currently work against the freedom of their users:
Debian, RedHat, Fedora
If you know of other unfree distributions, please report.
The following Linux distributions currently grant their users the freedom to select the better CD/DVD/Blu-Ray writing software:
Slackware, Gentoo, OpenSuSE, Ark Linux
Renaming was one of the options, dropping the patches the other.
