最新报道：Ethereum co-founder Vitalik Buterin formally laid out his stance on software releases in a new blog post on Monday, now advocating for slightly stricter "anti-copyright" licenses. This is a departure from Buterin's previous support for permissive licenses, which allow developers to use and redistribute the code "for any purpose, without restriction." Buterin explained that if derivative works are created and distributed by modifying or combining with other works, the new work must also be released under the same license, such as slightly more permissive "anti-copyright" licenses like CC-BY-SA and GPL. While still broadly opposed to copyright, Buterin's latest stance is an attempt to "use copyright to fight copyright itself" by requiring developers to use a release license that ensures derivative works also remain open to the public, he wrote. According to Buterin, his latest stance was influenced by the widespread adoption of open source code by companies like Google and Huawei, as well as the increasingly competitive cryptocurrency landscape. Buterin wrote: "Especially in the crypto space, where competition has become more intense and mercenary, we can no longer expect people to open source their work purely out of the goodness of their hearts. Therefore, the case for open source cannot rely on just "please"; it must also be accompanied by "hard power", that is, only allowing access to certain code to those who open their code." As an offshoot of the cypherpunk ecosystem, Crypto widely supports open source software that is able to freely use and remix existing code bases. However, this has sometimes been a tense issue, especially in the field of NFTs, where some artists have been seeking greater protection for their works.
