One way to look at this is that if you buy a bike, you should have at least basic understanding of its work and repair process. If you run a car, you should know the traffic rules. Similar in internet world, but only not explicitly implied.

Ignorant people should not be taken advantage of. But this is more like a principle than application. Currently, the internet is like a wild wild west. The more techy you are, more you can save your mental health. It is just the lack of awareness in people that make companies take advantage of them. IMO, Tech-literacy is a necessity, just like traffic rules or basic life support.
