No, he's spot on about the advantages of 'linear light' processing. It even makes a big difference to bilinear interpolation when you're doing texture mapping.

This is an incredibly confusing subject, thanks to the overlap of gamma as an encoding technique with all the other issues around color management. Poynton's Gamma FAQ is one of my favorite resources ( http://www.poynton.com/GammaFAQ.html http://www.poynton.com/GammaFAQ.html ), but even after five years working on image processing software I still have to make an effort to wrap my head around it all.
