I honestly don’t know - I have no evidence one way or the other.
However, FO:London was in development for a long time (years?), and Bethesda decided to release a (edit:) mod-breaking patch right before its release, b/c the TV show got popular and they wanted to say the game was still in development?
Maybe it wasn’t specifically to “screw over some mod devs,” but it didn’t help the community one bit.
Man, I loved that game (the DOS original)! I don’t remember the baddies being Nazis, but it would fit what I do remember from the rest of the game.
Just looked it up (it was originally called “Wolfenstein 3D II: the Rise of the Triad”):
In order to keep as many of the numerous game assets the team had already created from going to waste, Tom Hall came up with a new storyline which still incorporated the Nazi themes seen in the Wolfenstein series, however they would ultimately depart from plotlines involving Nazis, with the final narrative concerning a cult apparently inspired by the Californian folk legend of the Dark Watchers or ‘los vigilantes oscuros’.
Neat!
Edit: aw, man, quote your sources, ffs!
And it has already been patched out.
