Idk man we just saw a week ago how atrociously Linus used to treat people. Imagine combining that with enough greed to hold onto a billion dollars. Imagine what any of these people would be like if they were the type to ruthlessly exploit others to get rich. I think a billionaire Linus would be worse than Bill Gates. At least Gates is a nice guy.
It is the act of holding onto that much wealth that is immoral, not who is doing it. This is just fantasizing from a painfully neoliberal perspective: OP is imagining the world would be better if the good guys hoarded inconceivable amounts of wealth and exploited the labor of others.
