The crux of my post was about LEAVING THE FEET. Also, you betray your ignorance again because you apparently don't realize that an incidental contact with the chin is not helmet-to-helmet contact according to the rules.
If Eason had been flagged, I probably wouldn't have thought twice about it. Again, though, the entire point is that it is absurd to say that Eason's hit was worse than the one that got the guy ejected. Obviously, your reading comprehension skills are not sufficient to understand this, but maybe repeatedly typing it will help it start to sink in for you.
