US Senator Elizabeth Warren has been loudly calling for the breakup of America's big tech companies as part of her 2020 presidential campaign.
She chose to advertise her stance on Facebook, one of the platforms she's looking to dismantle, along with Amazon and Google.
In turn, Facebook took down four of Warren's ads that directly challenged its powerful position.
Facebook reversed its decision after Monday night (11 March) after Politico first reported it took down the ads.
A Facebook spokesperson said: “We removed the ads because they violated our policies against use of our corporate logo. In the interest of allowing robust debate, we are restoring the ads.”
Though her ads have reappeared, Warren has used this incident to push her message, saying she doesn't want a social media marketplace "dominated by a single censor."
Curious why I think FB has too much power? Let's start with their ability to shut down a debate over whether FB has too much power. Thanks for restoring my posts. But I want a social media marketplace that isn't dominated by a single censor. #BreakUpBigTechhttps://t.co/UPS6dozOxn— Elizabeth Warren (@ewarren) March 11, 2019
The above analytics are of an active ad that launched 11 March.
