I would respect the story based simply on his authorship. I believe he has a very good sense of what makes sense. I also met Peter Lee, author of the text book mentioned at the end of the article. I also attended Dr. Howson's class at the London School of Economics. This book, IMHO, is the very best overview of the status of Bayesian reasoning in evidence-based statistics.
Bayesian statistics is certainly controversial.
For some statisticians, this ongoing debate has the same intensity as a difference in religion or political ideology. But such differences are to be expected when the two schools have such substantial philosophical differences about the nature of probability. I've enjoyed learning about Bayesian reasoning. I have a better understanding of how strongly students are motivated to hear Bayesian conclusions in the midst of classical statements. I now teach classical statistics quite differently because of my Bayesian exposure.
