This bit put's it in context:
Based on the info at the time, he's not wrong, and wasn't wrong. Hell, it's unclear if De Palma want's it un-squished, so Mr. Harris might still be right and we're now getting a non-Director approved blu-ray.
I'm not surprised, my "Fat Head" joke comes from some of the posted screen caps where they look fat compared to some of the "squished" ones that looked more "normal". Some worse than others, there seems to be more inconsistency than just a flat squishing at 20 minutes in.
Or that maybe the...
Exactly, there's nothing for you to "buy". De Palma requested a correction, Criterion followed through with his wishes and found that it didn't work as they intended, and now there is a replacement as the fat heads is a better choice.
My guess is a mistake happened after DePalma approved the transfer and a check disc was made. I doubt Criterion will ignore it, I believe they have been pretty good about this stuff in the past.
