They are absolutely correct, as was a commenter that explicitly described what "privacy" means.<p>The issue is that corporations, like Facebook, have some very sweet "desserts" to entice people to abrogate their privacy. Alternatives have always given great privacy (spinach), but little in the way of a replacement for the "candies" that Facebook offers.<p>Facebook is <i>incredibly</i> valuable, and can afford to hire vast armies of engineers and psychologists, all dedicated to getting their "product" (that's users) to make themselves more "productive." Think farmers, giving hogs higher-protein, better-tasting food.<p>Until alternatives can provide a better "dessert" experience, and only offer spinach, then the vast majority of users won't come to them.
