I think we can say with some certainty that a company that fires a ceo and has a chairman step aside along with other board seats being open they are making room for a big investor of some sort. Any large investment comes with some level of representation on the board and control of the company management. If it is a buyout, they would not need the seats to be open because they would have all control after the buyout. There must be a big partnership brewing. If they just fired Nader, they would be talking and assuring investors all is good. They can be more silent than when Nader was ceo, but not this silent.
