The situation has not substantively changed, but your description of it is not
really accurate. There was and still is a "commercial license" which allows for
completely proprietary development without needing to allow end users to relink
the application against user-supplied versions of Qt. The free license is the
LGPL, which really is Free under all common understandings of that term. You can
use the LGPL license for commercial and otherwise-proprietary applications. You
just have to follow the terms of the LGPL like normal.
