Old news, at best; or, misleading hype, at worst.<p>Corporations are not extensions of the Public Square.  It is perfectly reasonable to require certain behavior as part of an employment agreement.  If I ran a hamburger stand, I would fire any employee who gave political commentary or rant while serving hamburgers.  And, if one chooses to air grievances against one's employer in the Public Square (i.e. on the Internet, or in newspapers), it is perfectly understandable that the employer would dismiss the employee.<p>To say "the Constitution does not apply to corporations" is in one way simply false: all legal entities (people, corporations, government) are required to adhere to the rule of law -- law founded on the Constitution.<p>But the bigger point is: the Constitution's purpose is not to protect individuals from corporations -- it's to protect us from _Government_.
