But in the stock market, it is almost impossible for companies like Anthropic or any successful startups not to become villains (profit first no matter what). Anthropic especially needs to burn huge amount of money, so they need a lot of funding. The only way to keep founders' idealism is probably to copy Zuckerberg. Divide stocks with and without voting-power and trade only no-voting stocks.
I'm not denying 95% of that, only saying that Zuckerberg didn't have any idealism to lose in the first place.
