Ex-employee sues Ethereum Foundation and Vitalik Buterin

An ex-employee has initiated legal action against the Ethereum Foundation, co-founder Vitalik Buterin, and four other respondents following a dismissal that occurred earlier this year. The lawsuit, submitted to the United States District Court for the District of Colorado on November 4, claims that the plaintiff faced unlawful treatment after disclosing a medical condition and questioning a directive linked to organizational changes.

The complainant, known within the community as "Nixo," led the protocol support team at the organization. According to the court filing, the dismissal took place on April 6, merely thirteen days after the individual revealed a cancer diagnosis. The legal documents further state that the plaintiff, alongside a colleague, had previously circulated an internal letter signed by dozens of personnel. This document expressed support for the general goals of the foundation's new mandate while objecting to a condition that required staff members to endorse the policy to maintain their positions.

The filing alleges that Bastian Aue, who served as co-executive director at the time, terminated the employment of the plaintiff and the colleague within thirty minutes of each other. The legal action alleges disability discrimination, retaliation, and interference regarding medical leave rights, with the plaintiff seeking financial compensation for lost pay and damages. Additionally, the complaint notes that staff members raised concerns over a reference to ritual suicide within the official mandate, though leadership reportedly explained that the wording was intended to be figurative.

Foundation Response and Mandate Details

In May, legal representation for the organization's Singapore-affiliated entity addressed the matter through correspondence. The lawyer rejected allegations of unlawful conduct or retaliation, maintaining that the separation agreement remained legally binding. Media outlets attempted to secure comments from the foundation and the affected individuals prior to publication, but did not receive immediate replies.

The organizational mandate in question was published in March to outline strategic goals for ongoing and future network developments. It emphasized open-source code, censorship resistance, privacy, and security measures, while directing internal focus toward research initiatives, protocol upgrades, and developer tools.
