According to a complaint filed on November 4 in the U.S. District Court for the District of Colorado, Kayleen Fulton (Nixo), former head of the Ethereum Foundation’s Protocol Support team, sued six defendants, including entities associated with the Foundation and co-founder Vitalik Buterin, alleging retaliatory dismissal and disability discrimination. The complaint says Fulton was fired on April 6 after disclosing her ovarian cancer diagnosis to management and organizing 53 employees to jointly oppose the mandatory signing of the Foundation’s mission statement (Mandate). It also cites a recording of a conversation with Vitalik, saying he was concerned that employees might influence the Foundation’s decisions by creating controversy. The allegations have not been ruled on by a court.
