I just think the revolution was a legitimate response to these grievances, and the fact that Western propaganda helped to foment it doesn't delegitimize it. The CIA's role doesn't negate the essentially democratic nature of the revolution or the heavy-handed repression carried out by the Soviets. In my opinion your interpretation removes the Hungarians' agency, and they become proxies rather than people fighting for their own political freedom and material conditions. It gives the impression that sending tanks into the streets of Budapest, and later to prevent a worker committee meeting from happening, was ok because Western Imperialism.
