You made it a point to talk about prior excuses... you didn't have to put those sentences in or link to Linus's post where he goes over the excuses that he's heard in the past. All of that is historical context that you decided to include. I want to make sure that the contextual view isn't overly one-sided since you decided to include it.
You could have just focused on the posts in the thread that talked to the current legal problems concerning signing off on the binary blob as part of a merge. Both of the Dave Arlie references I gave above include some discussion about the sign-off issue which you could have selectively quoted from. There's something significantly important there I think in the premise that Red Hat legal review has a higher bar to meet on sign-off into the upstream kernel than what is required to include in Fedora.
