Privacy and security are extreme privileges most people cant afford.
Yes. Hence the privileged should fight for privacy and security on behalf of everybody and not spread the nihilsm. For example, by supporting user-respecting companies or NGOs fighting for user rights.
Agree. Sadly this is not possible in much of the world, unless you absolutely not care for your life
Are there known cases of people killed or attacked for their support of digital freedoms? I don't mean becoming famous for political actions or organizing large events. I mean buying non-mainstream devices or sending a few dollars to EFF.
