Google is proposing a new technology called Web Environment Integrity (WEI) that would allow websites to request and verify information about a user's device and browser, potentially reducing ad fraud and improving security. However, the Electronic Frontier Foundation (EFF) argues that this technology could be used to compromise user autonomy and privacy, and could lead to websites blocking access to users who don't meet certain criteria. The EFF is concerned that WEI could be used to create a more closed and controlled internet, where users have less freedom to choose how they interact with websites. The proposal has sparked debate about the balance between security, privacy, and user autonomy online.
