What real-world privacy looks like. For years I don’t pick up the phone if I don’t recognize the number because usually it’s someone trying to sell me something I don’t want. Half the time I don’t even speak the language they leave in my voicemail. If only there were an effective do-not-call list that would track my preference to not be bothered. Companies I have done business with could still reach me, but they are in my contacts list. People knock on my door and ask me to donate to causes I oppose. They ask questions about my family demographics that are none of their business. Strangers approach me on the street and ask me to sign petitions or give money, with no idea whether I support their causes. I don’t want my personal information in a database, but if it means more efficient marketing so I don’t get buried in solicitations I would never consider, it might be a price worth paying.
