A coalition of civil rights activists on Monday were urging Twitter¡¯s advertisers to issue statements about pulling their ads off the social media platform after its owner Elon Musk lifted the ban on tweets by former U.S. President Donald Trump.

Trump¡¯s account, which Twitter suspended after the U.S. Capitol riot of January 2021 citing the risk of further incitement of violence, was reinstated over the weekend. Some 90% of Twitter¡¯s revenue comes from selling digital ads.

The groups in the Stop Toxic Twitter coalition complained that Musk had vowed to advertisers that Twitter would take a considered approach to reinstating banned accounts and convene a new content moderation council. No such council has been created as of Monday.
