Vitalik: Hoping for a Plugin to Display Final Product Price, Helping Consumers Avoid "Hidden Fees"
On November 20th, the founder of Ethereum, Vitalik Buterin, commented on a post by the founder of Uber, Travis Kalanick, regarding the tipping mechanism in a food delivery app. He said, "We need more 'adversarial' UI design, but it should be in the interest of the user. I hope that operating systems can have plugins that overlay the interfaces of all ride-hailing/food delivery apps, directly showing the all-inclusive price of each item, including taxes, strange additional fees, and expected tips."
Travis Kalanick, the founder of Uber, believes that tipping is a "hack" tool that exploits user psychology to maximize economic gains. On the contrary, Vitalik wants to help consumers avoid being deceived by the app's "hidden fees" and see the true price more transparently.
