This mod was hyped previously. DMCAing it right before its release date is a different kind of dick move; especially considering the game is vulnerable to an RCE exploit and the mod would likely patch it to have things move more securely.
The timing of this move makes me want to never buy another game from Activision (or Microsoft, by extension). Just such a blatant exploitation of the community.
I think that's been the move for awhile now. I have not or will not buy anything Activision or Blizzard, I would rather pirate if I wanted it that bad. But I'm finding that their games now a days are just copy and paste someone else's usually. This really was a dick move though.
