A top executive has argued that government regulation may be required over the position of search results in Google.
Government regulation is the absolute last resort. It might start with good intentions and the Government might have a light touch, but it would open the floodgates. Regulation only becomes more onerous and cumbersome over time. It stifles businesses ability to innovate, it slows progress and it takes some of the fun out of business.
In the free market, if Google screws up, we can go to Yahoo or Bing or another search engine. If they all screw up, a new competitor will rise. It is a self regulating system.
I trust an honest company (such as Google) more than any government, sadly.
