Last week, my colleague Adrienne and I examined a digital moral quandary: whether or not to install an ad-blocker. Ad blockers make browsing the web faster, more secure, and less of a drain on a phone’s battery; they also put a significant dent in web publishers’s business. After the newest version of Apple’s mobile operating system, iOS 9, permitted users to install ad blockers, they shot to the top of the company’s App Store.
