I think it gets exhumed, as you put it, because it never really died. Since the beginning of board wargaming the hobby has wrestled with its image. Sometimes the obloquy hurled at wargamers was unjustified, and the product of utter ignorance. Sometimes, there was fire to go with the smoke. I think one of the issues with WWII games, for example, is that the seemingly logical approach that most wargamers take, which is to separate the politics from the military history stuff, really is an attempt to what really can’t be done. Yes, you can carve off specific areas to focus on and leave other areas out, as long as the focus is narrow and the time frame is short. But ultimately, it all is of a piece, and you can’t fundamentally understand the battlefield performance of armies without considering the social, military, economic, and political context within which they operate. Unfortunately, for WWII, this brings people into areas where too many folks simply aren’t willing to do the heavy lifting necessary to compartmentalize when necessary without losing sight of the big picture. Too many want to oversimplify things one way or the other, and in my experience, the Nazi fanbois are by far the most numerous of these offenders.
