If programmers at NASA make a serious mistake on say the space stations's code, people will die and billions of dollars of equipment will be lost. The same cannot be said for a social website which serves a bunch of content. NASA has way more on the line than Facebook.
Well, if someone at Facebook screws up and inadvertently reveals certain names or locations or the existence of particular groups within some countries people get arrested, tortured, and die. Last I checked NASA screw ups only kill a couple of people at a time. So you are right, they are not even close to comparable. See how easy it is to make false equivalences? I am familiar with the referenced article and if anyone in the software industry outside of few specialized areas tried to push a process like that they would need to start the endeavor by polishing their resume because they would soon be looking for a new job.
Here's a great article on how NASA did development on the space shuttles code and the importance of process and quality: http://inst.eecs.berkeley.edu/~cs162/sp13/hand-outs/They-Wri...
