At its birth, the social network Gab issued a call for free speech. “We promote raw, rational, open, and authentic discourse online," said Andrew Torba, the CEO and founder, in an early interview with WIRED. And now, as it fights for its life, it’s doing the same. The site has been knocked offline after the Squirrel Hill massacre. The companies that run the infrastructure of the internet—PayPal, Stripe, Joyent, GoDaddy—removed support for Gab after the surfacing of vile posts on the platform from the alleged gunman, Robert Bowers. Torba, meanwhile, is still grabbing every bullhorn he can. Gab has posted calls to action on its homepage, which is now static; on Medium, which then banned it; and on Twitter, where some users have called for it to disappear soon, too. Even if there’s no internet, Torba still has the airwaves. “The answer to bad speech, or hate speech, however you want to define that, is more speech. And it always will be," he told NPR on Sunday.

To many people, Torba’s First Amendment absolutism is just a talking point. The site exists less to defend the ideals of Benjamin Franklin than those of Christopher Cantwell. It chose as its logo a creature that looks rather like Pepe, the alt-right attack frog. It courted people on the far right, and it became a haven for them. Free speech can be less a principle than a smokescreen.

Still, whatever one’s politics, the First Amendment exists—both as law and as a useful principle—to protect speech from politics. It’s a guide for constitutional scholars, as well as young CEOs writing and enforcing their terms of services. They may not have legal obligations to protect speech, but they have the moral obligations of creating a new public square. And in 2018, many of the most important decisions about speech are made by companies like Twitter or Facebook that have giant teams of people struggling with, and sometimes fumbling, the issues. Or, in other cases, they’re made by hosting providers and payment processors that have had the issue thrust upon them as they look at their P&Ls. In the summer of 2017, the internet infrastructure company Cloudflare decided to knock the Daily Stormer off the internet, promoting a thoughtful reflection from its CEO, Matthew Prince: “Literally, I woke up in a bad mood and decided someone shouldn’t be allowed on the internet. No one should have that power.”

He likely expected affirmation. That is, after all, why most of us post most of the time.

It turns out, as we now see, that lots of companies do have that power. The question is whether they are using it wisely. Should Gab have been knocked away? If your first principle is free speech, of course not. Anti-Semitism is not illegal, and providing a platform where anti-Semites post is not illegal either. Threats of violence are illegal, but Gab says that it does its best to remove them. Momentary political rage can blind people into abandoning sacred values. And there’s a practical argument, too. Pushing the alt-right off Twitter drove them to Gab. Will shutting down Gab just push people to Voat, or whatever comes next? (Then again, if that happens, is shutting Gab such a violation of free speech principles?)

There’s a bigger question at play, though, and it’s the most important one the technology industry has to deal with when it comes to the massacre in Squirrel Hill or the pipe bombs allegedly sent to targets of Donald Trump's rhetoric. Did the platforms radicalize the attackers? The United States government has a firm belief that jihadists can be radicalized online; can domestic terrorists, too? Would alleged pipe bomber Cesar Sayoc have sent those packages if he hadn’t found Twitter? Would Pittsburgh shooting suspect Robert Bowers have stormed a synagogue if Gab hadn’t sprung up?
