First and foremost, WF has been accused of acts that warrant a much heavier penalty in my opinion. With that said, there is nothing thus far to indicate that any other bank participated in this. I have multiple accounts at Chase bofa and TD and have never had an unrequested account opened.
Reigning in credit card churning, a process in which one customer manipulates the rules to their benefit, usually via MS, is prudent management on the part of banks. If you consider things like this, or asking a customer to pay their mortgage harassment that is truly sad.
