TiVo Selling Data on Users' Watching Habits

Gyppo writes: The San Francisco Chronicle reports that TiVo is collecting and selling data on what parts of broadcasts people are rewinding for review and what commercials they are skipping. "TiVo's Juenger said the Alviso company downloads usage data from a random sampling of about 20,000 set-top boxes each night. That data, he said, is stripped of any personally identifiable information before being mixed with other users' data for research and marketing purposes."
I seem to remember a very similar AOL privacy policy.
