If this is your point, sorry but your argument doesn't follow. There's nothing against the certification authority requiring 52 hours of training. And there's nothing against Zenefits cheating if they believe a certified expert is better than an uncertified one (and this is the argument underlying Mr. Friedman discussion).
Certification vs. Licensing is a complex discussion topic, I tend to prefer certifications over licensing, but this is definitively not the point with Zenefits.
