    Hi,

    In no special orders and it's not an exhaustive list:
    If you want to modify Qt without releasing your modifications.
    If you want to brand your application without having to mention that it uses Qt (note that this also valid for other LGPL libraries, you have to mention their use properly).
    If you want a full static build of your application without needing to provide the build artifacts so that your user can change the Qt version used as the LGPL allows them to.
    If you want to have support directly from The Qt Company.
    If you want to use some of the modules that are either GPL or Commercial.
    If you want to use stuff that is currently Commercial only.
    Etc.
