Had Hitler not able to stop Gestapo from sending von Braun to a death camp, not only history of spaceflight would have been delayed by decades, but the associated reputational bonuses to postwar Germany as "genius tech nerds that made a gross mistake" had been way lower. Not having the panopticon and just keeping freedom of speech and privacy as they are removes that type of risk. No way that serious neo-Nazis wouldn't think about that.
Unless Germany's serious neo-Nazis are especially wiser than America's equivalent far-right groups (which have played the political game well enough to achieve significant power already), I am not sure current evidence supports this supposition.
