[Interest] Qt Creator licensing for companies with Qt Commercial developers

[Tuukka Turunen]

Hi,

This disclaimer is because every case can be a bit special. We are trying to avoid a case where someone clearly violates the license and then comes with explanation, because N.N. said years ago that ABCDC is ok. 

The basic rules are simple:
- If you use Qt under open-source, check what LGPL and GPL (in case you use that) require you to do
- If you use Qt under commercial license, check what the commercial license agreement says, and ask in case it is not clear
- If you are involved in situation where both open-source and commercial Qt is used, do not mix them 

I think our licensing FAQ is quite clear, but I am naturally biased. 

Yours,

	Tuukka

    Because this is what users hear in MLs and forums, when they ask about Qt licensing
    issues. The recurring answer is: "don't know, don't understand, hire a lawer". 
    
    And because this is written in your FAQ: "It is always recommended to contact a lawyer
    familiar with open source licenses for a full review of your project to determine whether
    you can fulfill all of the obligations of applicable open source licenses".
