there are anti-trust laws in place for good reason which can handle these situations. while governmental control has to be avoided, at the same time regulation of monopolies isn't bad at all. it's a necessity for a healthy economy.
On the business model points, I think everyone agrees that no sustainable business model would be built upon search traffic. Doesnt mean a lot of people haven't got in and got out with million$ while they were riding the top of the serps, so many that are'nt making it now are already rich, not sustainable but they don't care,they're on a beach in the bahamas.
