According to the complaint from Anthony Pompliano: When they were trying to hire him Snapchat said they would hire 40 people under Pompliano for his growth team. Based on this promise he left FB to join Snapchat. He then found the numbers they were touting were not accurate and they were not committed to what they told him.
When the complaint gets to what happened starting the day Pompliano was hired and more specifically what happened when working there, it is blacked out for the next 8 pages.
After those pages it says he was fired after 3 weeks and Snapchat told employees, media contacts, and a company looking to hire Pompliano he was fired for being incompetent. This misrepresentation has cost him his reputation, money, etc.
