I feel compelled to side with the people who are saying the slavery comparison is a bit too hyperbolic, but in a sense we had become digital slaves giving ourselves away to every single website we see, and even I had fell victim to this; I’ve committed my entire life to Google and it’s great so long the idea every letter you type in GMail is probably being used to advertise relevant services is ignored.
The general consensus, and reasonable conclusion is it doesn’t matter what Google has on you, because if you’ve been on this planet long enough you either don’t care because you’re law-abiding, or don’t care because you realize no matter how hard you try to protect your online identity, it’s a vain and fruitless effort because the harder you try, the harder the Internet becomes to use.
Unless you live a fake dual life as a digital avatar not representative of yourself, there’s something of yourself — your real, actual self — on the Internet. There’s no stopping it, because even as you try to protect your online privacy, your real-world privacy is compromised with the use of credit and debit. Your money is in a bank which sells your identity to the highest bidder. Your workplace is compromised by a malicious actor who then releases a database containing your real name. Any place using your social security number for verification is ripe for picking and exposure by people who want to make dirty money with your real self.
Live long enough and you’ll realize in this day and age, the only privacy you really have is your ridiculously expensive accommodation six feet beneath the ground.
