I think you're referring to Communism-the-abstract-concept, whereas Orwell and OP are referring the Communism-what-actually-happened-everywhere-we-tried-it. The former is a utopic ruler-less society, the latter ends up being a totalitarian terror state brutalizing its impoverished citizens.
The very point of Orwell was recognizing this, and the fundamental similarity across totalitarian ideologies.
