I got an example, you are likely using it right now.
KHTML (LGPL, not GPL) taken by Apple to make WebKit (LGPL), later "rewritten" and licensed BSD for 2.0.
Apple did also the dirty trick of giving a single huge patch against the previous release of KHTML making it almost impossible to integrate back to the main codebase. Even LGPL can be abused. Lesson learned the hard way by the community.
And you now have everyone parroting how great WebKit is, nobody remembers the original team at KDE. It was brutal.
