it's more than the difference in how one mods the game, or disappointed expectations. there was a feeling after Legacy came out, that it would overshadow BC, and to some extent it has, many modders have moved completely from BC to L. One reason I think BCmodders don't like legacy is that in a lot of ways, BC has more potential than L, it might not have all the fancy shaders and what not, but it is far easier to mod. Also quite a few of our more prolific modders have been discouraged by actions of certain members of the L community, namely the people behind UU, because of their porting BC mods to L without permission. I don't know if I would boycott L because of UU, but, if I was a serious modder like DJ, and I saw my ship in another mod, without any mention of me, I would get pretty upset too.
