Freedom of speech laws apply to the Government, not private corporations. There is no "right" to free speech in the US between 2 non government entities. This would be illegal if a publicly owned entity had this policy (say a historic library or a public garden).... It's stupid and probably not enforceable, but its a civil court case.
