I have a friend / colleague who was a bit like this. It is a "see it to believe" situation. For her it was when she was at work and she watched her mouse stat moving on its own.

When she thought about how she never did anything bad on her work computer, but sometimes accessed her personal email... She got it.

And now she pays closer attention to things. Like in our city you're pinged via WiFi when you get on a bus, but you can opt-out or jut turn of your WiFi, so she does that. And she makes email aliases now too. Nothing too serious, mind you, but she is 50 and figuring this out on her own and then teaching her friends and colleagues about it which is way better than going down the rabbit hole. Now there's a bunch of boomers refusing to use Teams or access work email on their personal devices because she explained that they do have things to hide: the names and ages of their children and grandchildren, where they go for drinks after work, what they watch on YT, etc.

I don't get into it with people though. People just write me off as some nerd, which is not the case.
