背景:

自理查德·马修·斯托曼先生发起自由软件运动以来，自由软件及开源软件蓬勃发展，为人类文明发展起到
了巨大的作用。但时至今日以云计算厂商为代表的ToB类公司崛起，利用开源软件多于回馈，甚至不乏侵权等
各种破坏开源软件游戏规则的行为。为此诸多知名开源软件团队纷纷采用自己的方法来阻止这些行为，诸如：

https://mariadb.com/bsl11/
https://redislabs.com/community/licenses/
https://www.confluent.io/confluent-community-license
https://www.mongodb.com/licensing/server-side-public-license

但以上诸公司自拟的许可协议引起以OSI为马首是瞻的社区口诛笔伐，攻击他们非开源软件协议，因其未经过
OSI许可。但无视开源软件开发者生存维艰之事实，空谈开源正确解决不了问题。唯有在解决自身生存前提下，
方能持续更新维护软件。我们相信：

凡有助于他人的软件，无论其规模大小、功能完善程度、许可协议、源码开放程度，均值得肯定敬佩；
凡有助于作者完善软件的行为，无论其形式、参与度、先后、持续时间、贡献大小，均值得鼓励感谢；

藉此，我们拟定该开放软件（区别于开源软件）协议，以期抛砖引玉，寻求开放和商业之间的平衡点。

Background

Since Richard Matthew Stallman’s Free Software Movement, free software and open source software have been booming. It has played
a huge role in human civilization. However, open source software is exploited by the rising To-Business companies,
especially cloud computing ones. They take more than what they give back, and even breach open source consensus, such as infringement.
Hence, some open source software teams have to take actions to stop this, e.g.

https://mariadb.com/bsl11/
https://redislabs.com/community/licenses/
https://www.confluent.io/confluent-community-license
https://www.mongodb.com/licensing/server-side-public-license

However, those licenses are condemned by the community who follow the lead of OSI(Open Source Initiative) for not being approved by OSI.
Only talking about being open source but ignoring the struggling open source developers will not solve the problem for those developers.
Only under the premised of their survival, can open source software developers keep maintaining open source software. Hence, we believe that,

Any software that helps others, no matter what its size, functions, license, or open source percentage is, should be respected;
Any behavior that helps the developers, no matter what its form, participation, succession, duration, should be encouraged and appreciated.

Therefore, ZENTAO OPEN SOFTWARE LICENSE 1.0, different from open source, is drafted to seek a balance between being open and being commercial.
