Meta Platforms — the company behind Facebook, Instagram, WhatsApp, and Threads — earned $131 billion in advertising revenue in 2025. This revenue comes from one source: surveillance. Meta's business model is the most sophisticated consumer monitoring operation ever constructed, and understanding its scope is essential for anyone who cares about privacy.
What Meta Knows About You

Through direct usage of Facebook, Instagram, Messenger, and WhatsApp, Meta collects: every message you send (WhatsApp is encrypted but metadata is collected), every photo you post, every comment you make, every post you like, every video you watch (including how long you watch), every link you click, every search you perform, every group you join, every event you attend, every marketplace listing you view, and every ad you interact with.

But direct platform usage is only the beginning. Meta's tracking pixel — a tiny invisible image embedded in web pages — is present on over 30% of all websites globally. When you browse a shopping site, read a news article, or visit a health information page, the Meta pixel reports your activity back to Facebook even if you're not logged in and even if you don't have a Facebook account. Meta builds "shadow profiles" of non-users based on this tracking data.

Audit Your Site Free →In 2022, security researcher Felix Krause discovered that Instagram's in-app browser injects JavaScript code that can monitor all user interactions on external websites. When you tap a link in Instagram, instead of opening your default browser, Instagram opens the page in its embedded browser — and injects tracking code that can record every tap, every text input, and every page element you interact with.
Meta acknowledged the code injection but claimed it was for "aggregate analytics" and respects user privacy preferences. Independent analysis of the injected code showed capabilities that go far beyond aggregate analytics.

Automate Content →Signal offers end-to-end encrypted messaging with minimal metadata collection. The app is funded by a nonprofit foundation, not advertising. WeTalkin provides private messaging with zero surveillance. For social networking, Reddit offers pseudonymous community interaction without the behavioral tracking apparatus. Mastodon and the Fediverse offer decentralized social networking where no single company controls the infrastructure.
Deleting Facebook and Instagram is the most impactful digital privacy action most people can take. Meta's surveillance apparatus depends on user engagement. Every minute spent on Facebook is a minute of behavioral data feeding the most powerful consumer monitoring system ever built.
