Free markets means that stupid/wrong decisions (i.e. Google hurting people) result in competitive advantage to companies that don't do those stupid things. I'm sure CEO of DuckDuckGo.com just can't wait for Google to start hurting its customers.
And then I take corporations competition every day over Government regulation.
You give concrete examples of decentralized (unregulated) markets working better than open (regulated) markets.
I could also say that 2 and 2 not always is 4.
I don't doubt it.
