“These changes read to us mostly as a cover for not making the change that is most vital: ensuring politicians are not allowed to use Facebook as a tool to lie to and manipulate voters,” said Madeline Kriger, who oversees digital ad buying at Priorities USA, a Democratic super PAC.
Other groups, however, said Facebook had been more thoughtful about political ads than its industry peers.
“Facebook opted against limiting ad targeting, because doing so would have unnecessarily restricted a valuable tool that campaigns of all sizes rely on for fund-raising, registering voters, building crowds and organizing volunteers,” said Tara McGowan, chief executive of Acronym, a nonprofit group that works on voter organization and progressive causes.
Facebook has played down the business opportunity in political ads, saying the vast majority of its revenue came from commercial, not political, ads. But lawmakers have noted that Facebook ads could be a focal point of Mr. Trump’s campaign as well as those of top Democrats.
Facebook’s hands-off ad policy has already allowed for misleading advertisements. In October, a Facebook ad from the Trump campaign made false accusations about Mr. Biden and his son, Hunter Biden. The ad quickly went viral and was viewed by millions. After the Biden campaign asked Facebook to take down the ad, the company refused.
“Our approach is grounded in Facebook’s fundamental belief in free expression, respect for the democratic process and the belief that, in mature democracies with a free press, political speech is already arguably the most scrutinized speech there is,” Facebook’s head of global elections policy, Katie Harbath, wrote in the letter to the Biden campaign.
In an attempt to provoke Facebook, Ms. Warren’s presidential campaign ran an ad falsely claiming that the company’s chief executive, Mark Zuckerberg, was backing the re-election of Mr. Trump. Facebook did not take the ad down.
