I agree that it's low risk, but I don't think you can discount it completely. We have had public cases of high net worth individuals and people from prestigious companies doing immoral things (eg Kleiner Perkins, HP).
Point well made, but that risk is present in almost all circumstances where you are working for someone else (whether it's a traditional job and your boss makes suggestive comments/moves, or a client who insinuates they will give you more favorable terms if you do certain things, or a vc who will fund your idea/company if etc...). I would argue that the risk for a high net work individual is much higher b/c they have more to loose, so they would be less likely to do these things. Or maybe they're just better at getting away with it...
