People went ahead with it anyway. See, for example, PHORM in the UK.

> The company's proposed advertising system, called Webwise, is a behavioral targeting service (similar to NebuAd) that uses deep packet inspection to examine traffic. Phorm says the data collected will be anonymous and will not be used to identify users, and that their service would even include protection against phishing (fraudulent collection of users' personal information). Nonetheless, World Wide Web creator Sir Tim Berners-Lee and others have spoken out against Phorm for tracking users' browsing habits, and the ISP BT Group has been criticised for running secret trials of the service.
