The J. J. McCullough biography was created and deleted a total of five times on Wikipedia (with two different spellings of J.J.):
Each time it was deleted for "lack of notability". I believe he may not be telling the whole story in that video.
Apart from that, his criticisms are quite valid, if not exactly new. The video was discussed here the other day, see https://news.ycombinator.com/item?id=32793755
