If you earnt the full E120 an hour, this might be true.  But the reality with 
any employment is that the employer is actually making much more money than 
the employee.  So in this case, you are actually writing closed source 
applications for largely the employer's benefit, not your's nor free 
software's...

I'm simply encouraged by the small amount that has been LGPL'ed to adhere to 
KOffice rules.  But this seems contrary to your justifications for keeping 
code under the GPL.  Imagine if I wrote a KOffice application that wanted to 
depend on the Krita image library, would more be LGPL'ed then?

As Cyrille notes, this would unfortunately defeat the point of being BSD in 
the first place :(
