That's... not the point at all? This post is about a law that (to Sweeney's claim) would force founders to sell their controlling stock. This law wouldn't affect "de facto" control of a company -- it would affect actual stock-driven control of a company. The fact that Jobs did not have stock-driven control of Apple, and yet he was still able to "force his vision upon Apple" as you said, would make him a good example of why this law could be effective, since this law would not have affected Jobs' control of Apple.
