IMHO the hostile takeover of the ffmpeg project by the libav guys (Fabrice Bellard had to wield trademark to force them to rename the fork) and intense FUD campaign were much bigger issues.
I’m mad that a person, who bought a trademark for a project, then decided to act against the interest of the majority of the participants of the project,
Let me get this straight, your mad because Fabrice Bellard, the person who started ffmpeg, asserted his trademark on the libav folks because their fork initially used the name ffmpeg?
Seeing as your the maintainer for QuasselDroid, How would you like it if a group of contributors wanted to take the project in a different direction then you, so they fork it, call their fork QuasselDroid, and then say your branch is immoral, like you have throughout this page, I doubt you would enjoy this, and if you owned the QuasselDroid trademark I'm sure you would use it too.
With all due respect, you are not answering the question that the parent poster asked. If someone created a hostile fork of QuassalDroid, and made decisions that you disagreed with, I doubt you would be OK with them using the same name for the project. The right to fork is fundamental in open source, but there is no right to present someone else's work as your own, or to confuse the general public about which version of a software package they are downloading. People should be able to decide for themselves which software to download, not be fooled by someone passing off something different as the same thing. That's why trademarks exist. Enforcing trademarks is not bad or wrong.
But the majority of the project, the people owning the servers, technology, coding the most part, etc – those were the ones renaming to libav.
