The document discusses the "symbiotic web" model which describes the mutually dependent relationship between individuals and commercial enterprises on the internet. Enterprises have built business models reliant on collecting and using personal data, while individuals depend on free access to many online services.

The document examines issues around data gathering and uses, competitive pressures in the digital economy, and possible solutions like strengthening privacy laws and users' control over their data.
