The Washington Post Company told two parties interested in buying Newsweek that they shouldn't bother making an offer because they are ideologically unacceptable. I have no problem with people or corporations selling to whomever they want. But the Washington Post Co. is a public traded company. Were shareholders asked whether it was okay with them for potentially higher bidders to be locked out of the process for ideological reasons?
I would guess not. I've seen shareholder lawsuits based on weaker grounds.
