Just because an academicist has an opinion does not make it fact. That quote reads like a blogpost and with its lack of citation it might as well be. Yes, it sounds plausible. but well.

Let's assume it's true: your argument would be "intel made a mistake, but since they would have only made that mistake when doing stuff that appeases C programmers (would they have?), it's actually because of C."

Now, I think this is a bit of a stretch.

ETA: or did you mean that it has to do with C for that reason? in which case, ok, I see how you mean.
