justice4all writes to share that some of the recent complaints to the European Commission about Google have apparently been coming from Microsoft. "A lawyer for Microsoft confirmed that the software giant told the US Department of Justice and the European Commission how Google’s business practices may be harming publishers, advertisers and competition in search and online advertising. [...] 'Google’s algorithms learn less common search terms better than others because many more people are conducting searches on these terms on Google. These and other network effects make it hard for competing search engines to catch up. Microsoft’s well-received Bing search engine is addressing this challenge by offering innovations in areas that are less dependent on volume. But Bing needs to gain volume too, in order to increase the relevance of search results for less common search terms.'"
