| It's a good idea to follow the links before accusing someone of illegal behavior. Here's the link to the study again: [1]. This is specifically in reference to the reporting on quarterly earnings reports that we automate for the Associated Press. It's an objective summary of the financial performance of these companies that appears in news outlets across the country (for example, [2,3,4,5,6]). The companies being reported on have no influence over the content of the articles. From the summary: >These articles synthesize information from firms’ press releases, analyst reports and stock performance, and are widely disseminated by major news outlets within hours of publication...This study found a positive effect between the public dissemination of objective information and market efficiency.

I guess if I'd taken the time to read your original link we could have a more interesting discussion on whether pretty basic earnings information in a format more friendly and available to non-professional investors was adding noise to the market or providing a useful counterweight to the amount of free publicity that more prominent companies' earnings get. But I've probably already poisoned the well on this one.
