ACCC v Google is a settings-screen case. Users were not just reading a privacy policy. They were making product choices inside Android and Google Account screens, and the legal question was whether those screens gave a truthful picture of what would happen to location data.
For startups, the case matters because data risk often lives in product UX. A privacy policy can be technically accurate and still not save a business if toggles, onboarding text or account settings give users the wrong impression.
