Deserved or not, AGN has made a lot of enemies over the years. They have tried to steal ZC from us several times in the past.
Oh!, that's a story I did not know. By AGN you mean "Armageddon games", I thought that ZC was made by Armageddon games, I don't know why they should be stealing their own game. Unless there are various factions inside Armageddon games.

Oh well, it seems like a complex story, better not get the detail. So in this case, yes I can agree that close source is better as long as people are allowed to join the development team if they show some interest in the project.
