You do not have to pay licensing fees to oracle to use MySQL -- it's GPL.

You do not have to pay licensing fees to oracle to modify MySQL -- it's  
GPL.

You have to pay licensing fees to oracle to modify MySQL *and* keep the  
modifications private when selling the modified server code.

Note that an application that uses MySQL as a data storage but does not  
modify the MySQL source is not required to be GPL.  However, I think if  
you use the MySQL client code, it does need to be GPL.  Writing a new  
client that uses the correct protocol is not required to be GPL.  So the  
licensing of the client code *is* the thing most commercial users will  
care about.
