Why should he? I'm not a fan of Bezos, but he took all the risks involved in starting a company, so he's due the rewards. Employees accept a stable hourly wage or salary without taking in any of those risks. Big risk = big reward OR big failure.
He's a company representative. I have a feeling that being a Japanese company, Nintendo won't view his "worldwide company representation" very favorably since it will have an impact on Nintendo's image, which could have a negative impact on sales.
