Because someone takes an idea and uses that idea, either in good intention or to his own advantage, doesn't make the implementation true to the idea.
I can sit here and call the USSR a communist state because America said it was. Because even Lenin and the Bolsheviks tried to make it such, but that doesn't mean that it was real communism in any sense of the word.
Even Marx himself referred to this erroneous idea, and the USSR didn't even exist yet. The USSR, Maoist China was a form of state-sponsored capitalism, where the state and those close to it, were the abstract capitalist class.
