My antagonist asserts that the letter is written in the wrong person (i.e., the "we" at the beginning of the letter does not match up with the singular "John Doe" at the end of the letter). This is true, but I seem to recall that it's acceptable to have a person speak for, or on behalf of, a group of people or an organization if that person is part of the collective "we" and/or oversees that organization.

A. When speaking or writing for a group, it is perfectly acceptable to use "we" rather than "I." It is sometimes called the editorial "we." "I" at the beginning of that letter would not make much sense because Mr. Doe is not speaking for himself but for the entire organization. However, these are his words, and his name should be at the end of the letter. Otherwise, one would have to have the entire staff sign the letter.
