I am puzzled regarding the various rants (by politicians and others) of the type "we must break up Google"... Let me mention a couple of points which I never see addressed by people pushing this idea: 1. There exists a well established protocol/convention (robots.txt) that can be used to indicate to search engines that "these pages should not be indexed", thus preventing copying content from those pages. As far as I know, Google respect robots.txt. Companies (most often, news related organizations) that complain about Google copying their material can make use of robots.txt to prevent Google from indexing their content. Are they saying that Google does not respect this? ... or that complaining companies are clueless about this? 2. How do they think a pure Google Search company, without ad revenues, could generate revenues to sustain its operation? Search (for microsoft, yahoo and google) [and free email services] are most likely something akin to loss leaders / promotional tools. Legislating against anti-competitive behaviour (e.g. restrictions on advertisers to move their online ad campaigns to rival companies) is something that should be done if indeed it is occuring. However, everything else appears to be without logical foundation to me. But perhaps I am missing something...
