I try to make my relatives understand that this is something important, to put forward rational arguments, but they refuse me, saying that it would only complicate their lives, so it’s useless. I’m seen as the paranoid of the gang. So how would you convince your friends?
You can’t convince them, this is a situation where they’re going to learn the hard way, when their data is stolen.
But the analogy is using nowadays is with how the safety of people in cars wasn’t a priority a few decades ago both by ignorance and saving costs. Today it’s unthinkable to have a vehicles without seat belt, airbags, ABS, etc, and in a few decades it’s going to be common sense to protect your data.
Not sure I would personally make that comparison but maybe that could help some people. I suppose it depends how bad you think things can get without privacy…
I think there are better ways to make them unserstand. Just check every individual independently and avoid group policies.
