Vitalik: Previously Supported Permissive Licensing, Now More Focused on Copyleft

Odaily Planet Daily News: Ethereum co-founder Vitalik Buterin stated in a post that he has always supported permissive licensing, as he generally dislikes copyright from a philosophical perspective and greatly appreciates the copyleft concept of "using copyright against itself." However, his views have now shifted, and he is now more focused on copyleft. Since open source has become mainstream, it is more practical to encourage companies to embrace open source. Companies like Google, Microsoft, and Huawei are all adopting open source. In addition, competition in the cryptocurrency sector is becoming 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.)
