The author argues against Celsius because it 'feels' wrong? Well, I've grown up with Celsius all my life, and Farenheit just 'feels' wrong to me.
Everything is relative. The author deems 35 deg C as being "grossly hot", but that is just the average temperature to me where I live. He calls 0 degrees not even cold, but for me, that is almost unbearably cold.
Having a datum of 0 for freezing makes sense, especially for professions like flying (I used to be a pilot). Knowing that you are close to a point when water will turn from liquid to solid can be life saving, and I have no problems with using negatives to determine HOW solid.
