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?
Most people aren’t ready to accept the message of privacy importance. I would say that’s the vast majority actually. Many in my family throw all sorts of personal information into “online contests and signups”.
Privacy now is like climate change was 20 years ago…incredibly important, but hasn’t come to the forefront for most people, governments, etc. Say your message politely and only when welcomed, and otherwise leave people to make their decisions.
If you’re actually interested in changing people’s minds, it is an incredibly difficult and complex process, but you can start learning about it. Here’s an author whose podcast I follow and he’s doing really good work on the subject:

A lot of other comments talk about hitting him with some bullshit " gatcha" or some variation of scolding…which is all bullshit and counterproductive.
