Google is coming after critics in academia and journalism. It’s time to stop them.

It is time to call out Google for what it is: a monopolist in search, video, maps and browser, and a thin-skinned tyrant when it comes to ideas.

The imperial overreach of Google in trying to shut down a group of five researchers proves the point that the initial release from Open Markets was trying to make: When companies get too much power, they become a threat to democratic free speech and to the liberty of citizens at large.

In 1948, in the Supreme Court case U.S. v. Columbia Steel Co., Justice William O. Douglas explained that the traditional philosophy of American antitrust law is that “all power tends to develop into a government in itself. Power that controls the economy … should be scattered into many hands so that the fortunes of the people will not be dependent on the whim or caprice, the political prejudices, the emotional stability of a few self-appointed men.”

Google is forming into a government of itself, and it seems incapable of even seeing its own overreach. We, as citizens, must respond in two ways. First, support the brave researchers and journalists who stand up to overreaching power; and second, support traditional antimonopoly laws that will allow us to have great, innovative companies — but not allow them to govern us.

Google’s actions forced the Open Markets team to leave New America. But, thankfully, it did not succeed in silencing them entirely. Open Markets will continue on as a separate organization, which I will chair. Their work exposing corporate monopolies and advocating for regulation is more important than ever. Google shows us why.
