We have legitimate reasons why we don't share models, it's not because we're selfish twats, it's a preventative measure to ensure this mod doesn't spiral down the shitter.
Our player base is fragile enough as it is. We don't share models because it would almost certainly kill the mod. What we do is we share with teams, like N44, who have different goals (ie. Realism) for a little work. In N44's case, they animated for us, gave us MoW models and coded our entire AI from scratch. That's the sort of work that means N44 can help themselves to whatever EF model they please.
Ostheer models are being kept close to our chest so they don't become common place in other mods before the release of the faction. If we released our models to whoever wants them, when the Ostheer is released people are going to think 'Boring, already played with those units 4 months ago, give us something new', potentially destroying the factions before it's even released.
At the end of the day, these are our models, a lot of them are my own. I spend my own time making them, I spend my own time skinning them, I don't get paid for them so all I ask for in return is people respect the decisions I make in regards to what I do or don't do with them.
