My brother seems to not care about his online privacy. He registers to services too easily without pondering, he’s not outraged we need a fucking account to use a vacuum cleaner, it seems he doesn’t care about all the potential risks of having videos of our indoors saved in a cloud. I don’t have strong arguments to convince him that privacy matters other than “if someone gets that, you could be in trouble” and “it’s like having someone watching you h24” and so on. How can i persuade him?
I would refer to the recent FTC questions to “algorithmic pricing practices”. Long story short it was about some companies are using browser data, accounts data, etc. for “smart” pricing. Your brother may not care about someone watching him but I don’t think he wants to pay for the same goods more than others.
