Growing up I saw simple education around digital literacy. It amounted to the age old truth of “don’t believe everything you read on the internet.” However nowadays I don’t think schools are even talking about that. It seems like there are lots of assumptions that because the younger generation grew up with technology that they already know how to use it, which is far from the case. If you are not taught how to use technology, the products and their makers will teach you instead.
All that to say that if the basics aren’t taught, you def are not learning about all the risk you could put yourself in using services or sites in this way. When people say they have nothing to hide, this is like one of the few things that you probably do want to hide.
