Yes, it does look a lot better based solely on made-up numbers. Back in the real world, there's a 120 million dollar "investment" of which 1/6 is actually a no-strings-attached gift of cash money. That's an atrociously bad deal for the investor, and it's totally sensible to balk.
If the deal doesn't make sense, it doesn't make sense because the company is overvalued. But for a VC to agree that a company is worth X and then complain when 2% of that is used to de-risk founders is hypocrisy: the payout constitutes a smaller percentage of deal value than the VCs charge for allocating capital.
Any VC that finds these compensation figures absurd should have balked at the proposed valuation LONG before this point. This is in principle no different than de-risking founders 100k each out of a round valuing their company at over 10 million.
VC's take 2% of invested funds as a fee. The Airbnb founders are apparently taking 1/6 of invested funds as a "one-time dividend". You're not comparing like with like. VC management fees end up being less than 2% of the valuation of the VC portfolio assuming the portfolio earns any money at all.
The point of investment is that the money is supposed to allow the company to grow. When 1/6 of that investment isn't even invested in the company, but rather given as a no-strings gift, it's not an investment anymore.
