It's one of those situations in which one organization does it and everyone else realizes there are no downsides. It's probably more sincere that we'd like to admit. Sure, there might be a liability aspect to it, but why wouldn't you plaster it all over, even if it's a rubber stamp? At worst, it has no effect. At best, you help people--people who are likely your customers. Dead customers don't pay bills.
