Only Life mods are doing great due the huge free donation streams and it's popularirity. Owners/creators of such mod can easly go to work and make a living whle have alot of money on the side by donations for monthly expenses.
And what solution are you proposing ?,there isn't one. BIS monetization rules are killing communities and mods easly. Since the introduction of the monetization i ahve seen 60 to 70% off the Arma 2 Mod communitie sdissapear permanently.
