I can't help but feel this very well could be a side effect of modding being introduced for the console peasants -- theirs is a very controlled and locked down environment so it would make sense that Beth would want the same amount of control on PC. And seeing as almost every bloody game is made for those idiot boxes first and then made into a shitty, watered down port, it makes sense that Beth would stretch this asinine system to PC as well.
I have a feeling that the paid mod failed experiment is a sign of things to come. They'll lock down the games to cripple "unofficial" mods and only allow those with their blessing AKA those they can get cold, hard cash for.
