There was no way I could argue delete of [[David Shankbone]] without the very basis for the recognition and my fundamental belief in the purpose of Wikipedia to have been an absolute farce. Yes, I felt I could eat my own dog food.

Mr. Miller's "I'll eat dog food" statement means that he is disappointed that he's being treated this way by Wikipedians after making as much time and effort to support Wikipedia as he has.
I just figured he was misusing the phrase. I've always thought "eat your own dog food" meant "use your own products internally (within your own business operation), despite their flaws or inadequacies." That would only make sense in this context if it refers to his use of Wikipedia articles (i.e., products) to promote (or "inform people about") various things he's interested in, or perhaps directly involved in.
