There are a few completely fair points in there calling out what they are legally allowed to do (e.g. they are not directly violating GPL) and are doing (contributing changes back upstream, they claim "always"), that's about the only "right" this reader found.
Have some quotes that demonstrate the "wrong":
I feel that much of the anger from our recent decision around the downstream sources comes from either those who do not want to pay for the time, effort and resources going into RHEL or those who want to repackage it for their own profit. This demand for RHEL code is disingenuous.
Ultimately, we do not find value in a RHEL rebuild and we are not under any obligation to make things easier for rebuilders; this is our call to make.
Simply rebuilding code, without adding value or changing it in any way, represents a real threat to open source companies everywhere. This is a real threat to open source, and one that has the potential to revert open source back into a hobbyist- and hackers-only activity.
