According to a report by Jinse Finance, Ethereum co-founder Vitalik Buterin published an article titled "Why I used to prefer permissive licenses and now favor copyleft," in which he stated that he has always supported permissive licenses, aiming to maximize the adoption and dissemination of his work. Publishing under a permissive license helps achieve this goal, as it clearly indicates that anyone wishing to build upon his work can do so without concerns. From a philosophical perspective, he also dislikes copyright and appreciates the copyleft concept of "using copyright against itself." However, his views have recently shifted, and he is now paying more attention to copyleft. As open source has become mainstream, it is now more practical to encourage companies to embrace open source—companies like Google, Microsoft, and Huawei are all adopting open source. Additionally, competition in the cryptocurrency sector has become increasingly fierce and profit-driven. (Note: Copyleft is a concept and licensing method that contrasts with traditional copyright. Copyleft licenses require that derivative works based on the original must also be open source under the same license, ensuring that the work remains open and shared throughout its dissemination and development.)
