Uber has faced significant criticism for several "unethical" practices throughout its history, many of which were exposed in the 2022 "Uber Files" and continue to be debated in 2026. Key controversies include "Greyball," a software tool used to identify and evade government officials or regulators in cities where Uber was not yet legal. The company also faced backlash for its "Kill Switch" protocol, designed to cut off access to servers during police raids to prevent the seizure of data. Other ethical failures involve the misclassification of drivers as independent contractors to avoid paying benefits, and the 2016 data breach cover-up, where Uber paid hackers $100,000 to delete stolen data of 57 million users rather than notifying authorities. Furthermore, the company's early corporate culture was marred by reports of widespread sexual harassment and bullying, which led to a massive leadership overhaul and the eventual departure of co-founder Travis Kalanick.
