I wanna Commercial Secondary Development playground for bussiness
how can i not to violate MPL2.0 License?

我想基于@blocksuite/affine,模仿package/playground，做一个affine出来
I want to create an affine based on @blocksuite/affine, imitating package/playground

但是功上能我会增加很多自动化的功能
But I will add many automated functions to the product

然后进行商业活动
Then carry out business activities

我怎么才能不侵权呢？
How can I avoid violating the MPL2.0?

或者应该这么说
Or perhaps I should put it this way

我可以公开模仿playground的代码
I can publicly imitate the part of the code from the playground

但我如何可以被允许不公开额外的功能的源代码呢？
But how can I be allowed not to disclose the source code of additional functions?

I am a rookie just learned js for four month who wanna a job,so perhaps you could teach me how to avoid it.

in the end，I deeply love the performance, design, and aesthetic of this,which better than reactflow, quill, drawio

you guys have made a really great prj!
