How to contribute to Trisquel (and Software Freedom)

I've found some packages in Trisquel that do not respect the Free System Distribution Guidelines. I also created bug reports for Trisquel but I did not get a response. In one case this package was inherited directly from Debian[1] and I posted a warning not to include cadencii in GNewSense[2]. Recently I began to write a free software replacement for some proprietary programs and I want to make the software avialable for all Trisquel users. It should be better to fix the bug in Debian but I don't write access to any of the Debian Projects resources. And I don't agree to the Debian social contract[3], so I won't be able to become a Debian Maintainer [4].

I also think that a Skype replacement is important so I began building packages of gnunet[5]. There is a program called gnunet-conversation that could be included in a testing repository in Trisquel. This program is not included in Debian testing. A free replacement for Bittorrent Sync[6] could use the same infrastructure that the Skype replacement needs.
