SAN FRANCISCO - American broadcaster Public Broadcasting Service (PBS) has followed the National Public Radio (NPR) in quitting Twitter after the social media network labelled both organisations as government-backed media.

“PBS stopped tweeting from our account when we learned of the change, and we have no plans to resume at this time,” PBS spokesman Jason Phelps said in an e-mail.

“We are continuing to monitor the ever-changing situation closely.”

On Wednesday, NPR said it was quitting Twitter, in the first significant defection by a major news outlet since Mr Elon Musk’s tumultuous takeover of the platform.

The exit caps a week-long row over Twitter’s decision to label NPR as “state-affiliated media”, branding it in the same way it does major media outlets in authoritarian countries such as Russia or China.

Highly-respected in the United States, NPR had already suspended tweets from its main account as it waited for Twitter to change course, which it did by only modifying its label for NPR to “government-funded media”, a tag it also applied to Britain’s BBC.

In a short statement, NPR said all its organisational accounts “will no longer be active on Twitter because the platform is taking actions that undermine our credibility by falsely implying that we are not editorially independent”.

It added that “there are plenty of ways to stay connected and keep up with NPR’s news, music and cultural content”, urging users to other platforms, which it linked to in a final tweet.

Mr Musk has expressed deep disdain for news media for years, and recently installed an automatic response of a poop emoji to e-mailed inquiries from journalists.

“Defund @NPR,” Mr Musk tweeted on Wednesday afternoon, referencing the activist movement to “defund the police”.

News organisations have struggled to wean themselves from the platform, which remains a main communication exchange for celebrities, politicians and pundits.

A spokesman for NPR told Agence France-Presse that its journalists, as well as its affiliate radio stations, “will be able to decide on their own if they want to stay on the platform”.

NPR’s departure came hours after Mr Musk indicated in a BBC interview on Tuesday that the label decision was a mistake and that he would consider changing it to “publicly funded”.

He also addressed Twitter’s controversial move to strip The New York Times of its blue verified check mark after the company refused to pay to keep it.

From April 20, any legacy verified accounts on Twitter – which were established as authentic under the company’s old ownership – will have to pay to subscribe to Twitter Blue.

One of the reasons for this, Mr Musk said, was that he does not want Twitter to boost “some anointed class of journalists” who determine what constitutes news.

‘Roller coaster’

In the interview, Mr Musk said running the social media network has been “quite a roller coaster” and acknowledged “many mistakes” along the way, six months after he bought the company for US$44 billion (S$58 billion).

Assessing his time in charge, Mr Musk said it had been “a stressful situation over the last several months”.

“Were there many mistakes made along the way? Of course,” he said. “But all’s well that ends well. I feel like we’re headed to a good place.”

Mr Musk said the company was now “roughly breaking even” thanks in part to the crushing round of layoffs that slashed the payroll to 1,500 staff from 7,000 before the sale.

However, the billionaire pushed back at reports and studies that misinformation and hateful content were seeing a resurgence on the site since his takeover.

“You said you see more hateful content, but you can’t even name a single one,” Mr Musk said. “You just lied!”

Upholding his image as a hard-charging workaholic who sacrifices his personal life for his job, Mr Musk said he often slept on a couch at Twitter headquarters.
