Former Ethereum Foundation official sues Ethereum Foundation and Vitalik Buterin, alleging retaliatory firing and discrimination. According to a lawsuit filed in the U.S. District Court for the District of Colorado on November 4, Kayleen Fulton (Nixo), former Head of Protocol Support at the Ethereum Foundation, has filed a lawsuit against the Ethereum Foundation entity, co-founder Vitalik Buterin, and five other defendants, alleging retaliatory termination and disability discrimination. Fulton stated that she was fired on April 6 after disclosing her ovarian cancer diagnosis and helping organize an open letter signed by 53 employees opposing mandatory endorsement of Ethereum Foundation mandates. The lawsuit also cites a recording in which Buterin reportedly expressed concern that employees might manufacture controversy to influence organizational decision-making. The allegations have not yet been proven in court.
