the more people who are annoying / stubborn / obstinate / paranoid / crazy about it, the better off everyone will be. be "that guy." tell them it's the reason why they're not getting your money. tell them you don't have a phone. ignore them. go without it. it's not something you need. if it requires an app that should be enough for you to not want it. do whatever it takes to not download the app. people lived without apps for a long time. apps will be the death of everything you care about.
