禁止转售的开源许可证

我有一个开源项目，它是TFS的一个附件（即，它适用于开发人员和使用TFS的人员。）

当前正在使用GPL。但是我发现GPL并不能真正代表我要使用许可证做的事情。

我希望我的代码对所有想要使用它的人免费。如果修改并使用它，那也很棒。您不必开源修改内容。

但是我想阻止某人构建我的代码并出售它。或对其进行修改并出售。（任何想要这样做的人都必须与我协商单独的许可证。）

是否有一个开放源代码许可证可以防止转售，但允许下载该许可证的个人/公司完全无售卖使用？

不，没有这样的许可证。而且不可能。出售软件的能力是开源定义的关键部分。根据定义，任何禁止销售的许可证都不是开源的。

首先为什么？除非发生这种情况的可能性很高（在这种情况下，无论如何您现在都应该去看律师，看来您患有该I-am-afraid-someone-will-take-from-me综合征。

严肃地说，您在担心什么？如果有人免费提供您的代码，为什么有人会从您那里购买您的代码？而且，如果第三方增加的价值足以保证购买，您为什么要停止购买？换句话说，这对您（更大的生态系统）而言是一件好事，而不是一件坏事。

实际答案在这里：

我建议您使用以下BSD许可证，并添加第4个要点，例如：

    * Redistribution of this software in source or binary forms shall be free
      of all charges or fees to the recipient of this software.

但是，我不是律师，因此我进一步建议您由一位优秀的律师来管理。
