You are completely mistaken!  I'm more than happy to discuss this with you. My phone number is listed below. In the meantime please view https://www.qt.io/faq/

2.13. If I have started development of a project using the open source version (LGPL), can I later purchase a commercial version of Qt and move my code under that license?
"This is not permitted without written consent from The Qt Company. If you have already started the development with an open-source version of Qt, please contact The Qt Company to resolve the issue. If you are unsure of which license or version to use when you start development, we recommend you contact The Qt Company to advise you on the best choice based on your development needs."

    Like you need to get approval from the Qt company when not having been 
    Open Source before - it is the basic right of any seller not to sell.
    But your statement implies, that the Qt Company is blacklisting users 
    because of contributing to Open Source projects. Am I already 
    blacklisted because of offering code under an Open Source license ?
    How does this all fit to the Qt project, that is in parts based on 
    contributions from Open Source developers. Am I invited to contribute to 
    the code base, while not being allowed to buy my own contribution 
    afterwards ?
