I'm fairly sure development on QtWebkit started before Nokia acquired 
Trolltech.

What could Trolltech have done?  Webkit wasn't developed by them.  They 
wouldn't be able to relicense to Qt Commercial customers any more than 
Nokia can.

I can agree that lack of response to your queries about this is a 
problem, but it wouldn't change the situation.
