In what country does the author live?
Americans are so used to concentrated power that they don't bat an eye when they need to pay $100/mo for DSL, $2500 for an ambulance ride, or 1000%+ retail cost on lifesaving medication. Or when their boss (usually acting in the capacity of a multi billion dollar conglomerate) insists they pee into a cup or be constantly tracked and spied on in their workplace. Or when a single company siphons 100+ basis points off their tax payment (Lockheed, military budget). Or when we allow a handful of private companies to put human beings into prison. Or when five companies own nearly all television output. Or when three companies decide arbitrarily whether we can participate in the financial system (credit ratings). Or when 2% of every single transaction goes to one of two companies (Visa or MasterCard). Or when billions of dollars are spent each election cycle by only a handful of players. Or when a handful of individual bankers destroy the entire country's pensions and retirement funds, and are rewarded millions of dollars for it. To Americans, ceding power to a entity controlled by a half dozen stupendously wealthy shareholders is as natural as breathing.
Or, yes, when two companies (for most, just one company) control the flow of every single bit of information we see and hear online (Facebook or Google). Our allergy to concentrated power is the same one that a patient dying of AIDS would have against influenza. Though, let's be fair: HIV is a pre-existing condition.
This lawsuit probably sputter, though, because it doesn't adhere to the working legal definition of monopoly. Which itself suffers from the same blindness to power shared by the super-majority of Americans.
New laws for a new era? Look at who is on the judiciary. Look who is writing laws. Look at -- oh who am I kidding. We have made our choice the past few decades, and we are making our choice now.
