Minix 3许可证GPL兼容吗？

Question

有没有人知道是否Minix 3's许可证是GPL兼容的？这是一个BSD风格的许可，但我不完全确定它是否与GPL兼容。

Answer 1

这里是MINIX 3许可证：

前三个子句正是BSD 3条款许可证的子句，也就是与GPL兼容。第四条是多余的，除非著作权人明确允许，否则任何其他用途都是侵犯版权的。所以MINIX许可证是与GPL兼容的。

Answer 2

Minix 3许可证看起来非常类似于一个比GPL更宽松的标准BSD风格许可证，例如，它将允许商业上使用二进制形式的软件，而不必强制发布源代码。

它被认为是免费软件(就像任何BSD软件一样)，但是与GPL不兼容，主要原因是“广告条款”。GPL往往有更多的限制性。换句话说，虽然GPL确实允许软件的商业使用，但它确实强制GPL下的源代码在现在和将来发布(对于任何进一步修改它的人来说)。BSD风格的许可证允许发布一个二进制版本的软件，没有源，无论它是未经修改或已被进一步修改。
