In Privacy is Power, Carissa Veliz paints a disturbing picture of how much information all of us are giving away about ourselves and our lives and how that information is being misused. Even more disturbing are the ways in which that information is shared between companies, governments and other organisations.
This data gives others power over us, but there are steps we can all take, which are outlined in the final chapter of the book. Perhaps the most important is simply to spend more time offline (something I struggle to do). Others include being more wary of sharing, say no more often, use privacy tools and change the settings on your devices (even if it sometimes makes life more inconvenient) and, above all, demand privacy whenever you can.
This is an important topic and an important book. Highly recommended.
