I was discussing WFC with a friend yesterday. I likened it to the cable companies. Congress will occasionally pull their people in for a grilling and pretend they give a **** about the monopoly they have and the crummy customer service that comes with it. Nothing changes and repeat.
WFC is going to get fined by some of the states, and take a PR hit for a while, but not much is going to change. The reason they want people to have multiple accounts is to raise the burden of leaving. That hasn't changed, so I don't expect a large exodus.
