So, when you say Google loves competition, what you mean is that Google would be happy to gain market share and be unhappy to lose market share? OK...

When Google measures itself against other search engines it is primarily interested in measuring search quality and not market share.
Google has put a lot of effort into creating test query suites and other systems that can be used to evaluate search results and works to make sure that in each region and language it can out perform competitors. I don't know how effective the measurement is but I can tell you that Google takes providing the best search results seriously.
