No, not one year later - the same day. Hitler committed suicide on 30 April 1945, the same on which Dachau Concentration Camp and SS Complex was surrendered to US forces.
The article quoted from ends with these words:
But it’s interesting that a German shop can sell articles associated with communism without fuss, whereas a similar attempt to sell articles associated with Nazism would lead to a political row and possibly police action. Is that because communism is so obviously dead and Nazism, unfortunately, isn’t?
The conclusion is incorrect; Nazism is far more dead than communism, and has been dead for far longer. Communism still exists in a purely notional form as the official ideology of a number of governmentes, eg China. North Korea, Cuba, and as a residual political movement in some Western countries.
The reason for the paradox noted by the writer of the article is that, prior to the Cold War, there existed a political alliance between Communism and the Capitalist West for the purpose of defeating the challenge posed by the Axis nations. That alliance, which in Communist parlance was called "fighting fascism", superseded the essential economic rivalry between Capitalism and Communism.
Now the Communist economic system has collapsed everywhere, including in the countries that are still formally Communist, but with the end of the Cold War Communist political ideas seem to be enjoying something of a renaissance, even if not overtly, in the same way as they did during the wartime alliance between the West and the Soviet Union.
For example, the concept of "fighting Fascism" is now openly peddled by many Western politicians, with the term "fascist" used to denote Muslims who oppose Western domination. "Islamo-Fascism" is the buzz-word these days.
We see here the influence of various influential groups in the West which in the past, before the Cold War, flirted with Communism and now, with the end of the Cold War and of any suspicion of disloyalty, are able to renew their flirtation in a changed form. The dominant political group in the United States today, the Neoconservatives, is known to have a Communist pedigree, at least in its Trotskyist variant, which during the Cold War was easily transmuted into an acceptable anti-Soviet position, and now can again flourish in an anti-Muslim form.
So the nostalgia for Soviet-era bric-a-brac is fuelled by the feeling that the Communists, for all their faults in the economic sphere, were like "us" in their opposition to "fascism", an opposition that "we" are continuing against an alleged "Islamo-Fascism".
