You can’t have a vote to remove Kevin from the maintainer’s role. This isn’t a democracy.
Someone could fork the project - the license explicitly allows that - and demonstrate superior project management and game design skills such that most of the developers started contributing to that project. All of us, including Kevin, would love to see that happen.
However, in 3-4 years I’ve been following CDDA, I’ve seen a lot of people make angry noises about Kevin’s decisions but I haven’t seen anyone demonstrate consistently better game design or project management skills. Nor have I seen more than token efforts to fork the game and maintain the fork. Until someone is willing to bell that cat, I tend to take complaints about Kevin’s management style with a large grain of salt.
