Hi Thiago,

As I wrote a bit earlier, for completely independent projects/products it is fine that one is using commercial and one open-source. This is much more likely to happen in a big corporation than a small company, but possible scenario in both. 

Note that these really should not be same or in practice the same - or in any way depending, relating, using etc each other as defined in the license agreement.

See licensing FAQ question 2.7 at https://www.qt.io/faq/ and License agreement at https://www.qt.io/terms-conditions/

Yours,

		Tuukka

    And don't think of a 10-developer company. Think of a company with 20000 
    developers, with offices all over the world. If *any* of them buy a commercial 
    licence, does it mean everyone else must stop using the open source Qt? And Qt 
    Creator?
    
    How about contributing to Qt open source? Do they have to stop too?
