Let's suppose you built a cool new metasearch engine that refines Google search results. Now let's assume you explain to Google what you're doing *before* you have millions of users using and enjoying your system. And finally, let's assume Google bans you from freely accessing their search API in order to prevent a technologically adept, nascent competitor from reaching escape velocity.
What does that make you? An extremely talented technologist but naive businessman in my opinion.
And what does whining about Google's business decision in public make you? A whining, naive businessman.
We who make our living off of the two titans of search - Google & Yahoo - need to build our businesses in such a way as to stay in their good graces, at least until there's a better spread of search marketshare than exists today and for the foreseeable future.
