So, do I understand it correctly that if Redhat packages a piece of software written and maintained by someone else for their RHEL, they would share their RHEL revenues with them and pay for their work? Let's say the folks at AMD work so hard to provide a tool to make linux run better on AMD CPUs, now Redhat will not profit off of it by selling to their enterprise customers using AMD systems? The author of this memo just drank a lot of Kool-aid to believe in what he is writing. But, that doesn't make it right.
