If you ask someone if they are willing to let an impersonal algorithm analyze their data in exchange for a free service, the answer is generally yes. If you ask them if you can read their email and peruse their browsing history, the answer is almost always no. Exactly. That's why I put "privacy" in quotes. I think people are smarter than you give them credit for. I don't give out the password to my email account, but do I care that much if Google has some machine learning algorithm with a bunch of data points buried in there that I use the word "NYC" a lot? No, I really don't care. And yeah, they might get hacked and leak my emails to the world. That would suck. But that risk is worth it to me, and judging by the hundreds of millions of people with Gmail accounts, I'm not alone.
