I don't know and I wasn't there, but this sounds like the Steve Jobs wanna-be style of leadership. There is this myth of Steve Jobs leadership prowess and dictator style rule which probably has some element of truth, but everyone of these founders that try to emulate this myth thinking it will lead them to success.
You should nice to your employees, you should treat them with respect. You should give them reasonable working hours, reward them for their work, not fuck them and their families over for your vision of a how a silly picture site ought to be. Startup employees make dog shit for pay, and they get a good dog shit's worth of equity. A fraction of a percent is nothing unless the company sells for north of $50mil, maybe a nice bonus after that and not life changing until you're up in the hundreds of millions, a height few start ups ever reach. So just be nice. Startup employees are there for the experience, not for the money, unless they don't understand how startup equity works.
