>The poison pill only affects those who are looking to control the company in some way. Which isn't most large investors at all. So I doubt you will find any who will be concerned by this.
That's not the right way to think about it. Anything that scares off ambitious, optimistic activists from buying big stakes, will then suppress the stock value in general, which hurts all shareholders, including the smaller ones.
More broadly, going public is a tradeoff. You potentially give up control to outsiders, in return for greater share value (and the cash infusion). Moves like this go the opposite direction: decrease the potential for outside control, and with it, the upward pressure on the stock's value.
