the thing is that search engines are not considered to be an infrastructure technology per se. it is not as though the government is responsible for providing the search results on an “equal opportunities” base.
instead it is operated by a corporation part of who’s goals is to deliver superior search results to users. the algorithm is more geared towards users, not webmasters.
furthermore, google is not interested in someone “posting signs on how to get to their website” by manipulating google’s algorithm (which in fact what SEO truly is) as it skews the search results and does not show true representation of search results by relevance.
sooo, it’s an interesting example but doesn’t show the big picture. :hattip:
