Sonic co-founder Andre Cronje has echoed concerns raised by Polygon CEO Sandeep Nailwal regarding the Ethereum Foundation's (EF) funding practices. Cronje questioned the allocation of EF's resources, stating that despite spending over 700 ETH on Ethereum development, he received no support or acknowledgment from the foundation. This follows criticism from Ethereum core developer Péter Szilágyi about EF's compensation and governance issues. Nailwal also expressed dissatisfaction, highlighting a lack of support for core developers and Layer 2 advocates like Polygon.
