Looks like the WSJ article has some additional information, including this rather telling quote about the current company values, which seem rather different than the set of values Sacks espouses:

<<Mr. Conrad, 35 years old, is known for his brash style and the company’s operations reflected that. His company’s mantra — “ready, fire, aim” — is followed by many Silicon Valley startups meant to encourage aggressiveness.

Such a cavalier approach often works well for tech companies, such as Facebook Inc., whose motto in the past was famously “move fast and break things.” But it may have served Zenefits poorly as it operated in the regulated insurance industry.>>
