Amazon, Facebook, Google and Apple are "platform utilities" in Warren's sights because not only do they own marketplaces, they take part in them and in doing so, undermine competition and crush small companies.
The three ads that were taken down had the following message posted below them: "This ad was taken down because it goes against Facebook's advertising policies". Temporarily. Facebook later reversed its decision and reinstated ads published by the Senator. It said it restored them to help "robust debate". She called them monopolies that abuse their dominant position in the marketplace. "Facebook, Amazon, and Google", read the ads, which were placed by the campaign on Friday.
In another embarrassing gaffe, Facebook is restoring ads that promoted Sen.
"We must ensure that today's tech giants do not crowd out potential competitors, smother the next generation of great tech companies, and wield so much power that they can undermine our democracy", contends Sen.
Facebook briefly removed the three ads by Warren, which explicitly spoke out against Facebook's control over large swaths of our lives. Facebook's advertising policies prohibit the use of the company's corporate logo in ads.
"Curious why I think [Facebook] has too much power?" the presidential candidate said.
Facebook now requires political advertisers to prove they are in the United States by providing the company with information like government-issued identification. "Let's start with their ability to shut down a debate over whether FB has too much power", Warren wrote.
The idea that Facebook might be censoring political speech contrary to its interests proved irresistible to many Facebook critics, but the company said there was a much more mundane explanation.
The campaign also sent out a fundraising email off the development, with the subject line: "Facebook took down our ads".
"Thanks for restoring my posts", she tweeted.
There are strict rules governing who can use Facebook's corporate logo.
