Modding, copyright, and related issues.

Here, we come to a consensus that collaboration between mod authors and those groups/large mods is mutually beneficial (provided authorship is acknowledged, of course). Some gain publicity for their work, while others receive new materials for their mods, and so on. However, in your case, it seems that you initially view those who borrow content as "thieves" and the like, even though that may not actually be the case. That's why I'm writing about the negative perception.
