California Mandates Browser Opt‑Outs

California’s 'Opt Me Out Act' requires web browsers to include a one‑click, user‑configurable signal that tells websites not to sell or share personal data. Because Chrome, Safari, and Edge will have to comply for Californians, the feature could become the default for everyone and shift privacy enforcement from individual sites to the browser layer. — This moves privacy from a site‑by‑site burden to an infrastructure default, likely forcing ad‑tech and data brokers to honor browser‑level signals and influencing national standards.
