Twitter Pulls Back On Political Ads, But Pitfalls Await

Twitter announced an end Wednesday to political campaign and issue ads on its service, calling it an important step in reducing the flow of election-related misinformation.

But some of its users might face an unintended consequence or two.

Among those potentially affected could be public-interest nonprofits eager to reach an audience larger than their official followers, challengers, to incumbent officeholders, and — obviously — political consultants who make a living placing ad buys for their candidates.

Twitter CEO Jack Dorsey said in a series of tweets that paid political messages in the targeted environment that social media enables can be fraught.

“While internet advertising is incredibly powerful and very effective for commercial advertisers, that power brings significant risks to politics, where it can be used to influence votes to affect the lives of millions,” he wrote.

Security and privacy researchers and some Democratic politicians hailed Twitter’s decision as an important way to prevent campaigns from feeding streams of misinformation to targeted voters. The move drew a sharp contrast between Twitter and its much larger rival Facebook, which has come under fire in recent months for its policy of not fact-checking political ads.

Facebook CEO Mark Zuckerberg shot back quickly, using an earnings conference call Wednesday afternoon to offer an impassioned defense of what he called his company’s deep belief “that political speech is important.”
