Is Norman Finklestien correct when he says the Holocaust has become an industry for greedy people to make mone?

I agree with Norman Finkelstein when he says that the Holocaust is a "money-making machine" or "extortion racket" for Israel because the word 'Holocaust' itself was invented by the very same people to be used as a trademark. But the fact that he was a child of "Holocaust survivors" makes him have that bias of believing that his family were really exterminated in gas chambers. Maybe, maybe not, but how do you explain "execution gas chambers" with no shred of gas in them as proven by Fred Leuchter, Germar Rudolf, David Cole, and countless others who have been threatened with their lives for speaking these facts? The answer is very clear.
