The one consistant flaw I see in that whole argument, is that you make it all shareholder-centric.
What makes you think that that Keith makes all his decisions starting from the shareholder viewpoint and then going on from there?
Business first... the stock will take care of itself for the most part. I am not suggesting nor advocating that shareholders are or should be ignored. But in nearly any business, there won't be any benefit for shareholders if the business itself isn't taken care of first and foremost.
While I am quite certain that Keith and company do bear in mind the welfare of all shareholders in their decision-making, I do not believe for one instant that he makes business decisions based on how much shareholders are going to pelt him with nasty emails or how much they're going to whine.
Maybe you'd run a business that way, but if I found Keith were making that a priority in running Hemi, rather than focusing first and foremost on the business itself (independent of the stock), I'd sell it all today.
