    Default MIT licence of Ext Core. Is following ligal?

    Please answer to my question.
    For me it is very important.

    Ext Core is being shared with MIT licence.

    http://www.opensource.org/licenses/mit-license.php
    Open Source Initiative OSI - The MIT License:Licensing

    Pay attenton at these lines:
    including without limitation the rights

    copies of the Software
    So everybody has right to modify or not modify and even sell Ext Core as his own product?
    I need my own mini framework on base of Ext Core and maybe sell maybe not sell. I don't know.
    The matter is I will write new mini scripts and frameworks for one big commercial project.
    This project is a bit like google maps.

    It means company offer some scripts that generate something like maps.
    Maps could be free , could be not free, and some advertisement.

    Sorry for such complicate explanation.
    But I very need to know have I right to do all write.
    The matter is I am not allowed to use Ext Core in project cause service already uses JQuery.
    For the time of codding on Ext JS I realize that ExtJS is the best framework of js.
    That's why I get all ways, technicks, ideas and so on from it.

    At the moment all I need is allowing of writing my own code on base of Ext Core.
    I want full understand how Ext Core works inside I do my own mini framework on it base.

    Actiolly I already write mini framework on ideas of JQuery.

    But Ext Core is awesome framework and now I want to use ideas only from it.


    Sorry again for such difficult explanation.
    Please give me answer to question: Have I right on what I write?
    I think YES cause Ext Core is being sharing on MIT Licence.

    Here is what Ted Driscoll answered me 16 april and no more answer unfortunately.
    I didn't get is it legal or not.

    You can use Sencha to build applications, but you can not build a development tool or application builder.
    So I can't from Ext Core build new framework for my needs.
    But how about MIT licence.
    Ext Core is on MIT licence.

    I too asked (but on #extjs) about my current use case and after they redirected me to that same email destination, I got a similar "cold" response.
    My doubts were not cleared; but this approach is not ideal.

    My deduction is the sales department or whatever does not want to create fuss around the topic of licenses and by answering in a "cold" way they redirect the end user to the actual license.
    This is good.

    If you have doubts about the actual license application on your company and want a third party confirmation, a lawyer can specifically help you in clearing all your doubts about the license; which applies directly (this is why you do not really need the permission from Sencha to apply the license) to your use case, and if your company's project qualifies for MIT (although that response you got seems to not indicate so), you can go ahead and use Sencha for it.

    tl;dr: Applying the actual MIT license to your use case is enough to be able to know if you can use Sencha for your project. But understand very well the license before going ahead.

    Don't be a pussy. MIT license is short and clear, you can do whatever you want with it, including build a development tool or application builder. You are not required to give your modifications or add-ons.

    You could branch Ext Core, and call it Enterprise Ext Core, and put some meat to it, like creating a ton of cool UI widgets.

    JQuery also use MIT license.
