Change of paradigm
There is an infinity of shades between "just a search engine on the web" and "giant behemoth with way too much power". Laws are not well suited to handle the slow progression from one to the other over several decades. I'm not sure that Google is already at the level that it should be regulated like a public utility, and the question is probably not going to be decided by the courts of Ohio. But if Google keeps gaining in power the way it has until now, they will have to be regulated somehow. There has in fact been several laws that have been passed almost exclusively for Google, from the right to be forgotten to the French digital tax, not to mention the push to update safe harbor and copyright laws.
I think it is an idealistic misconception that laws devolve of simple rules which determine what is right and just. The world is way too complex for simple rules to determine that, and laws are just rules written to prevent issues which threaten the balance of society. Giant corporations like Google have found by chance some kind of loopholes in those rules, and they are threatening the balance of society, so new rules will have to be written.
