they have a "I am an idiot and forgot my password" button so people forgetting their passwords is no additional support, and if they allow longer password it actually makes them easier for people to remember and harder to crack, win win.
That is certainly not the only reason to have those rules; in fact, it's probably one of the least popular reasons.
It's done to keep customers creating short-ish passwords, which are likely to be more memorable, and therefore reduce the support load for password resets.
Whether this is actually effective or not is another thing entirely.
