As for A, how do I keep the majority shareholders from voting to bring in expensive management, rent expensive offices and equipment, then issuing more stock when they run out of money and repeating the process until I am diluted to nothing?
I mean, I've worked at many places where that looks like the company plan; they spend all their revenue, which is fine, but then they act like the investment money is revenue as well. It's like they plan for explosive growth, which is great, but they buy stuff that only makes sense if that explosive growth were real, and it ends up killing the company when the growth turns out to be only reasonable.
Sure, if the majority shareholders end up voting themselves huge bonuses or spending most of the company money on consultants that happen to be their friends, sure then I can sue them and maybe get something back; but the first case I describe is far more common, and the result, really, is the same.
