Wang Chun, co-founder of F2Pool, has criticized Bitcoin extremism in the ongoing BIP-110 controversy, arguing that it stifles innovation. In a post on the X platform, Chun expressed concerns that some Bitcoin supporters view scaling and feature improvements as threats, labeling them as "altcoin attacks." He warned that such attitudes risk turning Bitcoin into a rigid system with ideological overtones, rather than allowing it to evolve with technological advancements in DeFi, privacy, and payment infrastructure.
