Why gnu gpl/lgpl license for the lib conversion?

I feel much better with this, as with gpl and glpl your own application has to be gpl/lgpl. E.g. for lgpl you may not compile the lib into your own application as i understand, when you do it is the same as gpl. So for me that is no commercial use (not that that is going to happen soon :-) ).

Is there a possibility to get rid of the gpl/lgpl and use the original license or a bsd license?
