The Ethereum Foundation is under scrutiny following the departure of key developer Dankrad Feist to Tempo, a payments company supported by Stripe and Paradigm. Feist, known for his work on Danksharding, has expressed concerns about Ethereum's competitiveness against venture capital-backed networks and the foundation's appreciation of top talent. The situation has sparked reactions from industry leaders, including Polygon Foundation CEO Sandeep Nailwal, who criticized the Ethereum Foundation's internal dynamics and questioned its commitment to Ethereum. Former Geth developer Péter Szilágyi also pointed out issues of low compensation and governance within the foundation. In response, Vitalik Buterin has acknowledged Feist's contributions and the foundation's recent efforts to address these concerns.
