As maxerickson said, this possibility should be covered in the shareholder agreement. For that reason, any shareholder is already responsible for factoring in the risk of a buyout-by-vote when they buy shares. They were already responsible for making their own decisions as to "fairness" of that agreement. No information was hidden before the buyout, according to the article, so no "evening out" should be necessary, as far as I can tell.
