Old people spent almost all their lives living in a different world, where you could trust and believe in certain things. That world has dissolved just as their brains got too old to adapt to the change. It's hard for everyone to keep up, but for some people it's impossible. My father in law is like that, his smartphone is always full of crap because if he sees a popup advert telling him he needs to install something, he'll do as he's told. He can't tell the difference between an advert and a system message. He grew up in a world where most of the time you could basically trust what people were telling you, especially if it looked official. Modern technology and media has no consideration for such vulnerable people, except for finding ways to exploit them.
