The future of Twitter seemed to hang in the balance after its offices were locked down and key employees announced their departures in defiance of an ultimatum from new owner Elon Musk.
Fears grew that a fresh exodus would threaten the very existence of one of the world's most influential internet platforms, which serves as a key communication tool for the world's media, politicians, companies, and celebrities.
According to ex-employees and US media, hundreds of employees chose "no" to Musk's demand that they either be "extremely hardcore" or leave the company.
"So my friends are gone, the vision is murky, there is a storm coming and no financial upside. What would you do?" tweeted Peter Clowes, who refused Musk's final warning.
Musk, also the CEO of Tesla and SpaceX, has come under fire for radical changes at the California-based firm, which he bought less than a month ago for $44 billion.
He had already fired half of Twitter's 7,500 staff, scrapped a work-from-home policy, and imposed long hours, all while his attempts to overhaul the company face backlash and delays.
His stumbling attempts to revamp user verification with a controversial subscription service led to a slew of fake accounts and pranks, and prompted major advertisers to step away from the platform.
On Friday, Nov. 18, Musk appeared to be pressing on with his plans and reinstated previously banned accounts, including that of comedian Kathy Griffin, which had been taken down after she impersonated him on the site.
Musk however did not welcome back former US president Donald Trump, banned for inciting last year's attack on the Capitol by a mob seeking to overturn the results of the 2020 election.
"(The) Trump decision has not yet been made," he said.
'Not super worried'
Fevered talk of the site's imminent demise was driving record-high engagement on Twitter, according to Musk.
In a tweet, the South African-born billionaire said: "Record numbers of users are logging in to see if Twitter is dead, ironically making it more alive than ever!"
Musk added that the "best people are staying, so I'm not super worried."
Despite Musk's assurances, entry to Twitter's offices was temporarily closed, even with a badge, according to an internal message seen on US media.
In leaked emails reported in The New York Times, Musk asked engineers critical to the site's functioning to make their way to Twitter's headquarters in San Francisco to meet him in person.
Twitter did not respond to AFP requests for comment on the new measure.
In the ultimatum, Musk had asked staff to follow a link to affirm their commitment to "the new Twitter" by a certain time.
If they did not do so, they would have lost their jobs, receiving three months of severance pay.
Signs that government regulators were becoming impatient with Musk's handling of Twitter also grew, especially over the platform's ability to moderate content with a severely reduced headcount.
A group of US senators on Thursday said Musk's plans for the site "undermined the integrity and safety of the platform... despite clear warnings those changes would be abused for fraud, scams, and dangerous impersonation."
A top regulator for the European Union meanwhile said that Musk should be increasing the number of moderators in Europe, not reducing them.
Musk "knows perfectly well what the conditions are for Twitter to continue operating in Europe," EU commissioner Thierry Breton told French radio.
A spokesman for German Chancellor Olaf Scholz said the government was watching developments at Twitter "with growing concern" and reviewing its presence on the platform. (AFP)
