It's amazing that anyone actually still says this. The "I have nothing to hide" argument has been debunked repeatedly over the years. You have only to do a quick search for ( "nothing to hide" argument ) to find dozens of writeups explaining why that's BS. Please read at least a couple. People have different comfort levels of what they're willing to share, but everyone has things they don't want shared with others. If you really mean what you say, please post a naked picture of yourself here in your response, along with your address. Both of those are innocuous, right? We'd all find it entertaining, I'm sure. Later you can include a valid CC# as well. We'll see if you have nothing to hide.
Beyond the stupid arguments (both ways) above, you're conflating secrecy and privacy. I believe you're an intelligent dude from most of your posts here over the years, you really need to read up on this topic before making silly statements like the above. Here's just one (widely respected) article: https://chronicle.com/article/Why-Privacy-Matters-Even-if/127461/ Please do the courtesy of reading it before replying.
Ads? Who cares about ads? I just ignore them.
You're right on one hand, i.e. who gives a shit about the ads? Because it's not about the ads, it's about the data collection that underlies them. Google says you can disable profile-based ads, but they never allow you to disable the actual data collection and analysis of your personal data. Never confuse what you see publicly with what's happening behind the scenes.
I never send anything via gmail that is confidential.
I bet you're mistaken. Do you carefully use different email addresses for different purposes? Email is so pervasive that it's hard to imagine you don't send confidential information all the time. Do your doctors and dental offices have your email address? If so, Google has cataloged those relationships, along with every appointment, questions to your caregivers, responses from your caregivers, etc. Do you see your dentist every 6 months, or do you fudge? Google knows. Did you wish your friends a happy birthday recently? Now google knows their birthdays, and probably their ages. Do you never talk about anything personal over email about friends and family? Really??
