An Uber exec files to India to dig up dirt, we know they were buying email-mined data from unroll.me, and frequently monitored travel of journos, famous people and one night stands. They have a culture of digging up as much dirt on passengers as possible. I wonder what else they are still collecting (or quietly stopped), and what they're using it for, that doesn't have the explosive headline potential of medical confidentiality and sex crimes?
