A prominent anti-DEI campaigner appointed by Meta in August as an adviser on AI bias has spent the weeks since his appointment spreading disinformation about shootings, transgender people, vaccines, crime, and protests.

Robby Starbuck, 36, of Nashville, was appointed in August as an adviser by Meta – owner of Facebook, Instagram, WhatsApp, and other tech platforms – in an August lawsuit settlement.

Starbuck’s online posts have not changed in tenor since the “anti-DEI agitator” was brought into the Meta fold, and his Trump administration connections raise broader questions about the extent to which corporate America has capitulated to the Maga movement.

The Guardian repeatedly contacted Meta for comment on Starbuck’s role, and his rhetoric online, but received no response.
