Ha, maybe I just used this as an opportunity to complain about licensure; it's true that if Zenefits had cheated in order to get a certification it would still be illegal, and Zenefits would still have had a (smaller) incentive to do so.
On the other hand, Zenefits might not have bothered with certification since it wouldn't have been legally required, or the requirements might have been less silly if certified professionals had to compete with non-certified.
