You are right from 14th of January, 2009 add qt lgpl So the explicit goal of the LGPL is to allow “non-free” (e.g., proprietary) applications to use a piece of software without being forced to release the source code of the proprietary portions of the application to others. This is the fundamental difference between the two open source licenses.
