We had our annual local tennis tournament over the weekend, and this poor kid was one of the losers. He was actually doing OK against a better player, and even managed to pull out the first set. But then his opponent figured out that he had a weak backhand and it was all downhill from there. In the final set, I literally don’t think more than four or five balls went to his forehand. His opponent hit every ball as far wide as possible, and even though he knew where every shot was headed, it didn’t matter. His backhand broke down under the assault and he lost the final set 6-1.

Have you heard of Unroll.me? I hadn’t until they suddenly popped up in my Twitter feed because everyone was telling me to uninstall their app and never do business with them again. It turns out that Unroll.me is a company that scans your email and unsubscribes you from all your spam. Useful! And free! So how do they make money? By selling data to folks who will pay them for it.

In particular, it turns out that one of their clients is Uber, which was interested in keeping tabs on its biggest competitor, Lyft. Unroll.me helps by scanning email for Lyft receipts and telling Uber whether Lyft’s business is up or down. This is what caused the commotion.My initial reaction was: Duh. What did you think Unroll.me was doing to make money? I didn’t bother writing anything about it because I didn’t really care that much, but today co-founder Perri Chase (who’s no longer with the company) comes to the defense of her friend and Unroll.me CEO Jojo Hedaya:Anonymized and at scale why do people care? Do you really care? Are you really surprised? How exactly is this shocking?
