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.
That seems worse because it means they went out of the way to get so rich, rather than just having it handed to them.
