That's a level of control that you don't have in OpenBSD if the developer  
makes his code private.
A free software developer can't change his mind and make his code private  
after licencing it as free software.

The author of any program can change her mind about its licensing. For better  
or worse. What you probably mean is that any third person can take  
permissively licensed code and turn it proprietary (after modification or  
not).
