Earlier quoted context omitted.
Imagine if 70% of roads were privately owned by one company. That company, call it roadle, opened a restaurant chain. There is free parking in front of all roadle restaurants. There are always roadworks around all non roadle restaurants. This is what search is like today.
Not at all the same comparison. People that don't like Google or their additions to organic search results can simply switch to another competitor.
No, their comparison was perfect! They said roadle owned 70% of roads, not all of them. Sure, businesses can hope that they get their traffic from non-Google search, but if customers are going to Google for 70+% of search, that's a doomed business strategy.
Their point isn't that Google is bad for consumers, it's that it's unfair for businesses if Google is driving all the search to its own properties that you are trying to compete with.
