ironically portrayed much of the authoritarianism we see today in capitalist countries.
Which “capitalist countries” do you mean? I’d agree there is dangerously growing surveillance in Western Europe and the US, but this surveillance is much worse in self proclaimed anti-capitalist and “anti-western” countries like China or Russia or Iran.
I’d say 1984 is anti-totalitarian, and that has nothing to do with a particular political ideology.
