Big Tech vs Web3: Who Really Owns Your Data?

For years, Big Tech has built empires on the back of user data. Every search, every click, every interaction is logged, stored, and monetised—often without users realising the true value of their digital footprint. Google , Meta , Amazon , and other tech giants have turned personal data into a trillion-dollar industry.

But Web3 is challenging that monopoly. With blockchain-based identity solutions, decentralised social platforms, and user-owned data economies, the power dynamics of the internet are shifting. The question is: Are we finally entering an era where users take back control?

The Problem: Big Tech’s Data Monopoly

In Web2, users trade privacy for convenience. Social media, search engines, and e-commerce platforms collect vast amounts of data, using it to target ads, personalise experiences, and, ultimately, maximise profits.

• Facebook (Meta): Generates over 97% of its revenue from ad sales fuelled by user data.
• Google: Processes over 8.5 billion searches per day, tracking every move to refine its ad ecosystem.
• Amazon: Uses purchase history and behavioural tracking to dominate the e-commerce space.

These companies operate on a centralised model where user data is stored on their servers—vulnerable to hacks, breaches, and corporate misuse.

How Web3 Puts Users in Control

Web3 flips the model by giving individuals ownership of their data through blockchain technology.

• Decentralised Identity (DID): Users control their digital identity with cryptographic keys, eliminating the need for third-party authentication.
• Self-Sovereign Data: Instead of handing over personal information to corporations, Web3 allows users to monetise their data or keep it private.
• Decentralised Social Media: Platforms like Lens Protocol and Farcaster enable users to own their content and audience—without fear of being de-platformed.

For example: The Brave browser rewards users with Basic Attention Tokens (BAT) for viewing ads, shifting the power dynamic from advertisers to consumers.

Why This Matters for Marketers

For brands and advertisers, the rise of Web3 means:

• Better User Trust – Transparency builds stronger customer relationships.
• First-Party Data – Say goodbye to third-party cookies and hello to direct consumer interactions.
• New Engagement Models – NFTs, DAOs, and token-gated content offer innovative ways to connect with audiences.

Marketers who adapt to Web3 will future-proof their strategies, while those clinging to Web2 models risk falling behind.

The Future: Will Web3 Win the Data War?

While Big Tech isn’t going down without a fight—investing heavily in AI, metaverse projects, and regulatory lobbying—Web3 is gaining traction fast.

The question is: Will users embrace decentralised data ownership, or is convenience too powerful to resist?

One thing is clear: The fight for digital ownership is just getting started.

What do you think? Will Web3 disrupt Big Tech’s data dominance, or is centralisation too deeply embedded?
