Taken from the linked article.
Unless I'm very much mistaken, harmonics change as soon as you stop playing open strings, and so the "problem" dissappears one you fret a note. And as for the "muddy distorted rhythm sound", it seems that our Ed is using the neck pickup for his chords. Silly boy.
In my opinion, I wouldn't say that the linked article was a good "22 vs 24" discussion, just another Ed Roman rant about how everyone is crap, except his guitars i.e. advertising.
