The only time I've ever gotten someone "with nothing to hide" interested in data privacy was when I made an idle comment about ads I saw after sharing their IP address that were clearly targeted at them. That idle comment was accidentally 10x more convincing than any amount of rigorous argument. IME people who have "nothing to hide" get suddenly more interested in data privacy if it stops being an abstract threat. They see Google knowing their intimate secrets in much the same way they would their hairdryer. Until they dont. Unfortunately, that will probably happen for most people about two weeks before a stasi-like secret police takes full control over the country and by that point it'll have been about 10 years too late to start taking data privacy seriously.
