If Washington’s War on Google has begun, when will it end? The Justice Department is apparently gearing up an investigation of the internet giant. And for what reason exactly? That’s unclear. But one 2012 Federal Trade Commission analysis might give us a hint. It described Google as “engaging in tactics that resulted in harm to many vertical competitors, and likely helped to entrench Google’s monopoly power over search and search advertising.”

Overseas, the European Commission has thrice fined Google for business practices deemed uncompetitive. The most recent came last March when regulators hit the company with a nearly $2 billion fine for past “abusive practices.” The EC said Google “abused its market dominance by imposing a number of restrictive clauses in contracts with third-party websites which prevented Google’s rivals from placing their search adverts on these websites.”

But hefty fines and, say, better ad placement for Yelp and TripAdvisor, may hardly be punitive or radical enough given the dramatic complaints of some activists and policymakers. Alphabet-Google, tweeted Sen. Elizabeth Warren, “has too much power, and they’re using that power to hurt small businesses, stifle innovation, and tilt the playing field against everyone else.” (At minimum, she would “unwind” past Google acquisitions of DoubleClick, Nest, and Waze. Others would split off YouTube. On the right, nationalist populist leader Steve Bannon sees nationalization, at least partial, as a possible answer. Other activists would go further.)
