I agree with Woz's post. Especially with the new information that the letter wasn't signed, which indicates to me that it's not actually the shelter's official policy and perhaps from some ignorant/disgruntled employee.

Send a copy of the letter to a higher-up there asking for confimation of their policy and state that you will remove the link if you don't hear back from them. If you want to spend the time, also include the other advice about pointing out other business' revenue models from advertising, lack of true copyright protection, etc.
