Lots of good examples of the horrible nature of "big data". The writing is a bit too pop/magazine-styled for my taste (e.g., I cannot stand the phrase "If you think about it"), but the many examples and the author's observations are substantial and detailed enough for the purpose of making people aware. With such weapons being used to perpetuate and exacerbate society's inequities, this is yet more evidence that capitalism, and its supporting states, need to be replaced.
