The campaign to pull corporate advertising from Twitter, following its purchase by SpaceX founder Elon Musk, is being led by a network of left wing dark money activists with ties to prominent Democrat politicians and mega donors. An advocacy group formed in 2020 called Accountable Tech is organizing the pressure campaign, which has thus far succeeded in having the likes of Pfizer, Audi, General Mills, and other corporations pull their advertising expenditures from the platform.
