Phil Schwarz draws directly on his time as Tinder's CMO during the launch of Tinder Plus, speaking in detail about paywalls, swipe limits, and subscription mechanics, and he describes premium features as paying for the right to break the normal rules of a marketplace rather than simply paying for value.
