Orwell got very irritated, when American rightwing groups declared him as one their own. And he did reply when heard that, they were welcome to see his Labour member book. Orwell was he was young a communist, later on he got more disillusioned on the idea about the absolute regime, the right thought set etc. And he became therefore more pragmatic, in his preferred methods for social reforms.
I saw a link to this article about CIA changing of the film from 1955 ending

That ending was altered in the 1955 animated version, which removed the humans, leaving only the nasty pigs. Another example of Hollywood butchering great literature? Yes, but in this case the film's secret producer was the Central Intelligence Agency.
