Odaily Planet Daily News: Vitalik Buterin, co-founder of Ethereum, stated in an article that he has always supported loose licensing because he usually dislikes copyright from a philosophical perspective and appreciates the copyright left-wing concept of "using copyright to fight against oneself". However, this idea has now changed and he is more concerned about Copyleft because open source has become mainstream, making it more feasible for enterprises to move towards open source. Companies such as Google, Microsoft, and Huawei are embracing open source. Secondly, the competition in the cryptocurrency field is becoming increasingly fierce and profit driven.
Copyleft is a concept and licensing method that is opposite to traditional copyright. Copyleft licensing requires derivative works based on the original work to be open source and shared in the same licensing manner, so that the work maintains its open and shareable characteristics during dissemination and development
