This is being discussed fairly regularly, e.g.:


Maybe it's worth inclusion in some FAQ under wp.org...?  Also, it's bound
to become a serious  problem from  a political  and a technical point  of
view.   I recently discussed  this  elsewhere,  also  in  the context  of
WordPress < http://tinyurl.com/s7kbt >. The sooner people get choice,  
the better, IMHO. Transparency is among one of WP's selling points.
