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 actually did something similar to this before. After a breach I torrented the data to query my own creds (old passwords were leaked, from my pre random gen password manager days). I then searched my friend’s emails and messaged them asking them if their password was still “xyz”. I got a lot of “bro, wtf!?!” that day!
