楼越来越歪啊，怎么这么多人还给这种行为洗呢？真做过开源吗，别在这侮辱开源行吗，这不明显开源就是挡箭牌吗？开源收费无可厚非，但最根本的就是取之有道，而不是打着开源的旗号在这诱骗使用，自己没有开源精神别在这影响环境。我就给你们这帮智障粘贴一段什么是开源，省得你们自己再查好吧，给我仔细找 design documents 在哪：

Open source is source code that is made freely available for possible modification and redistribution. Products include permission to use the source code,[1] design documents,[2] or content of the product. The open-source model is a decentralized software development model that encourages open collaboration.[3][4] A main principle of open-source software development is peer production, with products such as source code, blueprints, and documentation freely available to the public. The open-source movement in software began as a response to the limitations of proprietary code. The model is used for projects such as in open-source appropriate technology,[5] and open-source drug discovery.[6][7]

还有一帮在这叫爱用用，不用滚的，您快歇会儿吧，求你赶紧去支持支持这种恶心的收费。你在这乱叫正好说明你没有开源精神。
