Many WGU students HATE these types of articles, because they undermine the legitimacy of WGU.
WGU was not designed for traditional students, it was 100% designed for working professionals, where WGU will only admit you with a reasonable amount of experience in your field.
WGU is regionally accredited, not nationally, and it's a non-profit. So it cannot be compared to University of Phoenix, ITT Tech, DeVry, etc.
It was founded by a group of governors out west, hence the name. They realized that there were many working adults who possessed a great depth of knowledge, from long working in their fields, yet they had no paper credentials to show for that knowledge.
Their model is competency-based, so you must demonstrate you posses knowledge in any given domain. If you can prove you do then you can test out right away, if you fail to then they offer a variety of resources to allow you to get up to par. In many cases classes are tied to obtaining industry certifications.
It's not for everyone, but it is a far cry from a "degree mill." Does it really matter if a person that has knowledge got it from sitting in a seat, paying ungodly amounts of tuition, or if they got it from life experience? As long as a bar is set, and you can meet it, then that should be what really matters.
Just my personal experience, from having attended the university. Unfortunately life sidetracked my completion, but I hope to return one day soon, and complete my program.
