Can someone explain to me why people return money to investors? Legal reasons? Altruistic reasons? Selfish reasons (maybe that keeping it would hurt their reputation and make them feel guilty)?
Each case is specific though, but at some point, if the product has no growth and key talent has left the building, even if you do have six-seven digits in the bank, new employees are not exactly knocking on your door, users are not over-running the servers, remaining employees quietly send out resumes, so what would you be spending that money on?
