The EARN IT Act is a proposed US law that could lead to the scanning of online messages, photos, and files for child sexual abuse material, potentially compromising user privacy and end-to-end encryption. The law would create a government commission to establish best practices for internet companies, which could include scanning user data. Critics argue that the law's language does not adequately protect encryption and could lead to false accusations and abuse. The Electronic Frontier Foundation is urging people to take action against the bill.
