Which to me seems much the same as companies attempting to suppress bad reviews (even if such reviews are warranted) be it by deleting them, denying service to those who post them, or even in rare cases issuing groundless legal threats and-or C&Ds; all of which makes the entire review system suspect at best and near-fraudulent at worst. It's simply corporations trying to control what people say about them, and this seems to me like more of the same.
A corporation is not a person and does not have feelings, and thus in theory cannot take offense over what someone says/writes about it unless it crosses the legal line into libel and-or defamation. We have courts for that, and due process.
