Earlier quoted context omitted.
It's inspiring to imagine subversive writers bravely speaking truth to power, when the reality is they're just observing the mundanity of their own time, then later as world shifts into insanity their commonplace objections to ordinary injustice look like unspeakable challenges.
Not saying that does not happen sometimes. In this case, Orwell was a volunteer in the Spanish civil war. I think that places him pretty strongly in the speaking truth to power and not hypocritically.
Just saying that most of us cannot see the implications of our thoughts in our own epoch. Most dystopian authors playfully hope they're wrong. So I think when Orwell penned his best anti-fascist works the world was already on an optimistic post-war trajectory, seeing an "arc of history that bends toward justice". Nobody had anticipated technofascism is its emerging forms.
