An open letter has been sent to EU and US regulators urging them to ban surveillance-based advertising, citing its invasive and privacy-hostile practices. The letter, signed by 14 businesses, argues that such advertising undermines competition, harms consumers and businesses, and can erode democracy. The signatories claim that alternative forms of advertising exist and can be implemented without significantly affecting revenue. They believe that businesses can thrive without resorting to privacy-invasive practices.
