Well, I don't think such an attitude over missions is something to be encouraged. DCS, like so many simulators, is plagued by a lack of good playable content. If the community were to get so weirdly possessive about their missions that they wouldn't allow other people to play them the small pool of available missions would get ever smaller.
This is a game me and my friends would like to play more but it's very much limited by the small number of available missions. Simulators often leave the game part to the players (to their detriment, in my mind) and if the players don't share there's no game to play.
