At least in Orwell's 1984 the Tele-Screens were imposed by an external authority. The present day is much worse than he could have ever imagined.

Everyone over the age of 13 carries a high-quality camera with them at every waking moment; in fact, they regularly shell out for higher-quality cameras as technology improves! Not only that, but they've been operant-conditioned to take photos and videos of any interesting events and send it to the central servers of spy companies like Facebook and Snap, where they will be stored permanently for the foreseeable future - and they do this all for free!

I think it's also definitely the case that social media increases peer pressure to conform. If you say the wrong thing, have the wrong political opinion, you will be publicly shamed.
