Also, the judge has already decided that even Gmail users are generally unlikely to understand that their emails are being intercepted for Google's business purposes.
Using the contents of people's email to support an arbitrary business model is too broad according to the judge.
If we allow advertising as a legitimate reason to allow machines to read your email, why not also allow Google to offer credit scores, insurance ratings, HR evaluations, and services to private detectives?
If we say analyzing your communication is ok as long as it makes money for the service provider and the service is free, we open a Pandora's box. Google (and anyone operating an SMTP server) would be able to sell HR reports to recruiters, insurability scores to insurers, predictions of criminality to police departments, infidelity scores to private detectives, etc. Advertising is not a specially protected business model.
Somehow I don't think we'd say that they haven't intercepted the email.
Shannon information is always measured relative to a receiving context in which it the symbols are understood, and information content is related to the inverse of the probability of observing a particular signal as assessed by the receiver. So from that perspective vinceguidry has a reasonable point.
However really the question being asked is something more like 'data density' and that is generally what people are talking about when the term 'information density' is invoked.
Edit: I see that the original article does indeed refer to Data Density, and that HN title is just wrong.
