That dastardly media

From Maisonneuve magazine's MediaScout, on George Jonas's National Post commentary on the Conrad Black trial:

Then he launches into the serious part of his commentary, calling the prosecution a “sorry lot” whose “dubious evidence … rested on the slender foundation of browbeaten government witnesses butting their beaten brows against documentary evidence.” Wow. Not even a half-hearted attempt at journalistic objectivity to be found there.

Why does MediaScout expect George Jonas's commentary in the Post to display any journalistic objectivity? Has this person ever read George Jonas before? Does he or she know what a commentary is?
