@Penn95 - yes, some of their stats were slightly off (actual yield on ED is indeed closer to 96-98%, not 100%), although the paper stated that Regular Decision tends to yield “slightly less than 50 percent year to year.” Their statement on RD, when assessed on a “year to year” basis is probably accurate - most years Penn’s RD yield has been slightly below 50%, especially if you go back a few years, no?
The valid notes about the slight statistical inaccuracies aside, the Daily Pennsylvanian’s Editorial Board raises some great points. Yes, they could’ve presented more data (especially data on how diverse the RD applicant pool is - on all fronts), but I don’t think anyone doubts that the ED pool tend to contain more people from privileged backgrounds, and contains restrictions/rules that may adversely impact the poor more than the rich.
Re background of ED at Penn, this article on “the Early Decision racket” has been referenced in the past, and is helpful here:

Penn, in some ways, is the poster child for the irresistible temptation for using ED, much to institutional benefit and applicant loss. You get great students, they commit early, yield is super-high, and you can use RD to fill in the gaps.
But here’s the problem: when do you have too much of a good thing? Penn used to fill maybe 1/3 of the class ED, and that number has crept up over the past 15-20 years. During this time, schools have fought hard to look more similar to one another than ever before. Institutionally, for example, Northwestern has never been so similar to Penn as now, and Penn has never looked so similar to, say, Harvard. ED, though, is ruthless: pick your true love out of many similar-looking suitors now, or forever hold your peace.
This year, with Penn on track to fill 55% of its class ED, it looks like there are two application options:
Apply on time (ED), or apply late (RD).
In recent years, the applicant pool has noted this signal, and ED apps continue to spike at College Hall.
