"GS has every right to create a forum where customers can air grievances" Yes. They have no right to make it look like they represent the company in question, though. GS's defense is that they mostly do represent such companies...and yet they use the same setup for companies that may not even know their site exists. Consumer-grievance forums have been around for years. They don't impersonate companies.
