Remember the Internet.org and FreeBasics movement which was used to muddy the Net Neutrality waters? Guess which startup was excited about Internet.org

> Onavo’s founders, Guy Rosen (CEO) and Roi Tiger (CTO), are on board with the plan. “We’re excited to join their team,” the two wrote, “and hope to play a critical role in reaching one of Internet.org’s most significant goals – using data more efficiently, so that more people around the world can connect and share. When the transaction closes, we plan to continue running the Onavo mobile utility apps as a standalone brand. As always, we remain committed to the privacy of people who use our application and that commitment will not change.”
