Google does not have their own expertise in anything other than the very specialized branch of computer sciences and experience in building humongous data centers. All their "knowledge" in that "Knowledge Graph" is scraped from other sites. How in the world could you have so much hubris to slap in the face the very people you depend on?
Wall St expectations.
You're right however, all of Google's data is not really their own. Webmasters don't complain because they get traffic but when that stops, especially if they get stomped on at the same time, I absolutely see a growing revolt of all things Google happening eventually.
The only real game changer I can see happening in the *near* future however, in the next 2-3 years, would be Facebook launching their own search engine and suddenly becoming a major source of new traffic for websites. The ad dollars would be split between adwords and facebook even more as webmasters embrace facebook a little more... and google a little less. I would welcome that with open arms as well for the sole reason that it would leave me less vulnerable to the whims of one company.
You see it all coming like a freight train, but does the Google engineer?
