I need to prepare a lecture for my colleagues about Qt Development, and one of the topics is licensing. But it's a very controversial topic, since the three Qt licenses make its licensing hard to understand. I tried to read "Qt Licensing(Qt Licensing)":http://qt.nokia.com/products/licensing) a few times, but I'm still confused.
So, I'll start with a some questions:
Can I develop and deploy closed-sourced commercial applications without buying a commercial license of Qt?
A more specific question, since the answer may be different: can I develop and deploy closed-sourced commercial applications without buying a commercial license of Qt, distributing it with the original Qt libraries, without any changes on it?
My personal projects are free and open sourced, but I need these questions answered so I could convince (or not...) some coworkers to use Qt on their commercial projects.
