I live in the U.S. where many people can't turn off their devices because they're addicted to them. And because they don't really have off switches.

This is one of the things that Orwell did not anticipate: there's no need to threaten people with prison. People will voluntarily set up the spying infrastructure in their homees if they perceive that it's cool or that it makes life a little more convenient for them. They'll even pay for it!

Again, choosing not to switch off a device because you're "addicted" is not the same as "can't turn off".

And every device has an off switch. At the very worst, you either unplug it or don't charge it or throw the damn thing out.

Where you're absolutely right is the voluntary aspect of modern surveillance. If we had a BB style telescreen, it would annoy people to the point of revolt, but package it with "content" and everyone is cool with it.

Always on devices like Alexa (and its clones) are becoming more and more common. Even my parents in their 80s (hardly tech early adopters) have one. If there's a problem with the prediction of 1984, it's the assumption that the threat is government. But William Gibson and other cyberpunk authors got that corporations are the real source of power.
