That ended quickly. Good. The Washington Post reports:

The legal battle between Twitter and the U.S. government ended Friday as the Department of Homeland Security withdrew its demand that the tech company release information to identify an account holder whose tweets have been critical of President Trump.

The lawsuit threatened to become a major battle between Silicon Valley and Washington over free speech. But it was over almost before it began. The social networking site filed a lawsuit Thursday to protest the order, saying that it violated the user’s First Amendment right to free expression. But Twitter dropped its suit Friday, saying in a court filing that because “the summons has now been withdrawn, Twitter voluntary dismisses without prejudice all claims.”

Alt Immigration thanked Twitter and the ACLU.

We want to thank @twitter and @aclu for standing up for the right of free anonymous speech. Thank you resistance for standing up for us. https://t.co/6PdwZIJ2xP

Ron Wyden sent a letter urging Customs and Border Protection to do an internal review into how and why CBP issued the summons.

The Post continues:

Courts have traditionally given a high degree of protection to political speech, including the right to speak anonymously or with a pseudonym. That includes, in many circumstances, government employees who are critical of the agencies for which they work.

“This is just, as best as I can tell, the government trying to figure out who is expressing criticisms, and that is chilling,” said Marc Rotenberg, executive director of the Electronic Privacy Information Center.

If the goal was to quiet the dissent, it seems to have failed. The number of followers for the Twitter account grew from “over 32,000” to more than 150,000 in less than 24 hours.

I’m one.
