* Foundem -- the British price comparison site that is backed by ICOMP, an organization funded largely by Microsoft. They claim that Google’s algorithms demote their site because they are a direct competitor to our search engine. The reality is that we don’t discriminate against competitors. Indeed, companies like Amazon, Shopping.com and Expedia typically rank very high in our results because of the quality of the service they offer users. Various experts have taken a closer look at the quality of Foundem’s website, and New York Law School professor James Grimmelmann concluded, “I want Google to be able to rank them poorly.”

* SourceTool/TradeComet - SourceTool is a website run by parent company TradeComet, whose private antitrust lawsuit against Google was dismissed by a federal judge earlier this year. The media have noted that TradeComet is represented by longtime Microsoft antitrust attorneys, and independent search experts have called SourceTool a “click arbitrage” site with little original content.

* myTriggers - Another site represented by Microsoft’s antitrust attorneys, myTriggers alleges that they suffered a drop in traffic because Google reduced their ad quality ratings. But recent filings have revealed that the company’s own servers overheated, explaining their reduced traffic.

"Because we can" isn't always sufficient justification.
