Right-wingers often claim that Orwell changed his beliefs at the end of his life. They won’t provide any evidence though, because there is none. His statement that everything he wrote was in support of Democratic Socialism was written while he was writing 1984, because he was being accused of betraying the revolution by the people who would become tankies a few years later.
Orwell had his own views on who betrayed the revolution, being a Spanish Civil War veteran and having escaped the country after being warned that the Stalinists had put his name on an execution list for fighting for the wrong group (he fought in a Trotskyist international brigade but felt more solidarity with the anarcho-syndicalists, despite not completely agreeing with either of them).
