What does this irony reveal about Orwell's political philosophy?

The irony is that the Animals turn out to be little different from the humans they liberated themselves from. If anything, Napoleon was more of a tyrant than farmer Jones. Orwell was making a commentary about the best intentions of a communist state, like Russia at the time, becoming the opposite of a socialist utopia. Orwell thought that universal equality can’t exist because those in power will inevitably succumb to temptations of greed and the euphoria of power.

Thank You.
