That's revisionist history. Those people who voluntarily affiliated with Nazis were generally forgiven unless they benefited from the affiliation in ways beyond mere survival. The Nazis had a nasty tendecy to kill those who opposed them, so "affiliating" and even "accomodating" with Nazis was a valid survival technique so long as affiliation or accomodation did not turn into mutual cooperation. Many people in the French Resistance were officially "affiliated" with the Nazis in some way; this is part of what made them so effective. The same is true of those who helped Jews flee from Nazi-controlled areas.
