最新报道:Ethereum co-founder Vitalik Buterin said in a post that he has always supported loose licensing because he generally dislikes copyright from a philosophical perspective and appreciates the copyright left-wing concept of "using copyright against itself", but now this idea has changed. Now he is more concerned about Copyleft because open source has become mainstream and it is more feasible to push companies to open source. Companies such as Google, Microsoft and Huawei are embracing open source. Secondly, competition in the cryptocurrency field is becoming increasingly fierce and profit-driven. (Note: Copyleft is a concept and licensing method that is opposite to traditional copyright. Copyleft licensing requires that derivative works based on the original work must also be open source and open in the same licensing method, so that the work remains open and shared during the process of dissemination and development.)
