May I try to point out the elephant in the room? Most KDE applications and
libraries are copyleft, with tremendous effort and contributions from a
wide range of people. Since most of them belong to more than one author, it
is not possible for a maintainer to simply re-licence an existing piece of
kdenlive is still falsely advertised by others, based on Duckduckgo results
(already reported to duckduckgo using their Report Ad button, but not sure
how many reports does it take to trigger an action from them). This may be
prevalent in other common search engines.
