It seems that you miss the basics of Copyright.

In order to find out whether Redhat really owns rights, you first need to find 
out whether this code is copyrightable at all. Small portions of code just 
become a part of the original work unless they have a sufficient level of 
creation.

If you stay with OpenSource, even larger parts are no problem as minor 
contributors do not get the right to decide about the "way of marketing".
Minor contributors just have the right to get payed by the right percentage of 
the whole, which is a simple computaion in the OSS world.
