I'm not a purist, either, especially when it comes to media that entertains me. (Loved, for example, the first two seasons of The Borgias despite all the considerable liberties.) But yeah, Hydra... enough said. I'm glad you approve of Weizsäcker as the one most likely to point this out. :) And that you enjoyed the story in general. I really enjoyed the research (including a trip to the Deutsches Museum, where I hadn't been in years, to check out the Z3 reconstruction and the Z4) and writing it.
