If the developers had listened to all the LFS purists, we would still be playing S1. I understand that you want to protect your precious sim, I love it just as much as you do, but in my opinion you are being all too conservative about it. You can't stop the progress (positive or negative) and standing still at the same place for ever isn't going to solve anything. What you should be much more concerned about is how to handle this situation around mods before it explodes to uncontrolable chaos of crappy models and shitty textures. Rather than bitching about mods and people who want it, you shoud think about how to organize things so that both sides can profit out of it in the future, because at this point, consider it your last chance to do something about it. Sooner or later, LFS will have mods and you will just cry about it.
Now don't take me as your opponent or something, I am too for conservation of the good old LFS as it is now, but I also want new possibilities to explore. High quality community content. I was talking about it earlier and I am tired of repeating myself over and over.
Please, just don't sit, curse and wait until the devs release the modding tools, prepare yourself for it now, organize yourself and take control of the whole situation and you all will have my support.
edit: how come that I missed the riot when bf1 was introduced and new sounds were introduced? i'm sure it was helluva lot of protests
