You don't need "big firewalls" and government-sponsored censorship to control information. There are softer ways [0] to press for a narrative that's advantageous to you and ways that are way less visible [1].
Note the claim how supposedly none of the "interventions" happen in the English language, just like the NSA supposedly never spied on US citizens. That statement was rooted in the Smith-Mund Act, which has since then been reformed [2] and it's been an extremely noticeable shift in the English language online discourses.
Just like language itself is a filter, anybody who only speaks English is dependent on trusting what English sources translate and tell them. While other-language sources often paint a very different, usually way less polarized, picture.

I avoided it somehow in high school, as I did most books, and ended up reading it in my early 20s. Now over the past 10 to 15 years I've seen it starting to come true in scary ways, albeit not exactly as was predicted (which is to be expected of course).
It's also just a good book! It builds to a tremendous climax, and the ending is just as good and unexpected as any good story today. Highly recommended.
If you like audiobooks, the one narrated by Frank Muller is great. Audible has it for $10 but it's of course hobbled with their DRM. There is a copy of the Frank Muller reading floating around on torrents, but a better solution is to just buy DRM free. There is a DRM free version narrated by Simon Prebble that I haven't listened to, but it has great reviews (all audiobooks from Downpour are DRM free btw): https://www.downpour.com/1984?sp=12482
P.S. If you care about your freedom, when possible buy DRM free from places like Downpour. Paired with an app like Listen Audiobooks, I find the UX to be even better than Audible (it's a great app: https://play.google.com/store/apps/details?id=com.acmeandroi...)
Actually I've read The Prince and I got carried away by the ideas in the book. Maybe I shouldn't read 1984 after all? Anyway, I'm just interested in politics, but not planning to enter politics.
