If the stock price doesn't go up Amazon (and every other company compensating with RSUs) will have to fund raises out of their own pockets. Yes I'm aware stock-based compensation is also an expense. But as I understand it, that expense = the initial value of the grant. So if the stock price goes up it's like the employee got a handsome raise funded entirely by Wall Street.
