Stop. Don't flame me just yet.

My answer is "no, absolutely none - any potential benefit is much less than the risks/issues associated."

Am I right? I'm asking out of thoroughness for exceptions before I make a blanket statement to a client on the matter.

I guess it's a bit like robbing banks. If you get away with the money then I guess you could argue that's a benefit to the robber. But not something you'd want to encourage. 

I can't think of any reason why a company would want to be involved in spyware / adware other than their own illicit gain.
