Ethereum co-founder Vitalik Buterin has addressed community concerns regarding his preference for niche decentralized tools over mainstream options. Buterin criticized the mindset of chasing widely-used tools, citing the rise and fall of Liberty Reserve as a cautionary tale. He emphasized the importance of resisting blind reliance on centralized products that compromise user data and may have backdoors. Instead, Buterin advocates for building and using tools that protect user sovereignty and freedom, aligning with the core spirit of Bitcoin.
