Apple trolls tech industry with huge billboard advertising iPhone privacy outside CES conference

Apple has bought a huge billboard at the world's biggest gadget show to troll the rest of the tech industry. Towering over Las Vegas, where the CES 2019 technology show is being held, the ad points to Apple's privacy policies in an apparent dig at competitors such as Google. "What happens on your iPhone stays on your iPhone," the message reads. At the bottom of the board is a link to Apple's privacy website, which lays out the ways that "Apple products are designed to protect your privacy". "At Apple, we believe privacy is a fundamental human right," it reads.
