Kupor's mentality stems from dealing with co-founders who leave right after they complete their 4 year vest, well before IPO/acquisition.[1] While they certainly laid a foundation for the company, there's a lot of work still to be done to get to a liquidity event. Is it fair for them to leave with a huge stake and let the other co-founder(s) and employees figure it out? This is where he gets to phrases like "no longer contributing" or "wealth transfer". Essentially he's saying the vesting schedule doesn't capture everything an option should incentivize. Having said that, I think he's over-applied this mentality to regular employees with much smaller stakes. It is reasonable to expect a founder to stay 10 years with a company. Not most employees.
