Probably because it was overpopulated by Jews to begin with, similar to how Jews are overrepresented in Marxist think tanks and other groups in the United States, having written the majority--if not 100%--of the founding documents or working out the educational/sociological grounds for all this "white people are evil" and "tranny sex is good" stuff we see in the schools.
Denying it, or saying it's a conspiracy theory, doesn't help the Jews confront these uncomfortable facts.
Orthodox Jews themselves sometimes note that God picked a stubborn and wayward people... as bible history backs up too. It was, there is an excellent case to make, intended to underscore the magnanimity of divine salvation.
But whatever role Jews played here, they didn’t invent the ideas of this revolution. They just provided much of the mental playground for it once it was invented. Such is brilliance that it is a sharp two edged sword.
