In other words: Will there be an employee uprising at Twitter?

The social network favored by President Trump has a complicated political ethos. Jack Dorsey, Twitter’s co-founder and chief executive, is an outspoken supporter of liberal causes, and the company has reveled in its centrality to viral progressive movements — the Arab Spring, #BlackLivesMatter, #metoo and #MarchForOurLives were all animated by forces on Twitter.

But Twitter’s real-world effect has hardly been a liberal panacea. Around the world and particularly in the United States, Twitter is used every day to infuse misogyny, racial and ethnic animus and conspiratorial thinking into mainstream news coverage.

And Twitter is obviously the favored tool of President Trump, who has recently picked up the pace of his tweeting. The president often uses the service to seed threats and falsehoods into the world — falsehoods that are then picked up and amplified by supporters and critics alike, ricocheting to deafening effect across the news.

The tension between Twitter’s liberal employee base and the service’s role in news and politics has only heightened recently. For years, Twitter’s business looked gloomy; with about 300 million users, it had a fraction of Facebook’s billions of members, and it struggled to convince advertisers and the mainstream public of its relevance. But in the last 18 months, Twitter found a new focus in the news. The company shed ancillary businesses and tweaked its central feed to highlight virality, turning Twitter into a bruising barroom brawl featuring the most contentious political and cultural fights of the day.

The strategy is working. Users and advertisers are returning, the stock has made steady gains, and thanks to Mr. Trump, no one questions Twitter’s relevance anymore. As BuzzFeed News declared last month, “Twitter is making an unexpected, somewhat miraculous comeback.”
