Hydra is a good company with some talented people, and is much too large for one - or even two, three or four - people's exodus to adversely affect.
The CEO (Zac) has a brilliant business mind, and he built an empire (no pun intended, CPA fans) with sound judgment; if it was his decision to move the company this direction, it is probably beneficial in the long-term.
I know Zac & some of the people that were let go - as well as those that left voluntary - and though it is a major loss, no one person is bigger than the company at Hydra. They are essentially a machine with replaceable parts, and will be able to find people to fulfill the roles that were vacated.
I can not imagine the internal chaos that must be occurring at the company as this was definitely a jolt to morale (in my opinion), but Hydra will succeed, will continue making money, and will continue to be a good resource for affiliates and advertisers alike.
