> By your own logic why would anyone invest in anything that wasn't public if you were just throwing money at some dude that wanted to do something that wasn't in your interest?
Because usually you get preferred stock, that means that all the 'crazy' non-profit-oriented things that the founders might be doing are still done with their money, rather than yours.
There's just a difference in both incentives and philosophy, isn't there? If the company is controlled by a private person, they're not obliged to make decisions that are 'best for the company'; and anyone choosing to go along for the ride is expressing trust into that persons ideas and goals. (And any contractual terms they set in their shareholder agreement; but the owners can refuse terms that misalign with their vision)
>It sounds like you're saying, it's sad that founders don't get to spend money anyway they want without carrying about the wishes of who gave them the money.
No; I'm saying that if as a founder you want to be able to spend money any way you want, you do not want to go public.
