He was a capitalist who appropriated the rhetoric of the commune where he had lived.

Commune implies at least an informal socialistic environment, if not actually primitive communism. So the sentence means that he spoke as a member of such a community, but was in fact devoted to capitalism and the private accumulation of wealth. That's the best surmise i can offer you without more context.

Thanks! The sentence is used to describe Steve Jobs.

I know nothing of Mr. Jobs.

I wanted to comment, Miss Chan, about how well you're doing with your English. You are very fluent--i'm impressed with how rapidly you progress.

Thanks!!!!
