I have a hunch it's more about form than content. If the trip report had been a one-paragraph "We climbed Baker via Coleman-Deming, great conditions, good views" type of things no one would have said much. The guy's trip report, however, lays out a million and one things they did "wrong" but doesn't take the appropriate "oh my god we fucked up and almost died" tone. It's more along the lines of "we fucked up and got lucky, so we rock!"
So you have someone both detailing the mistakes they made and appearing cocky about it instead of kissing the feet of the 11th Essential. That's bound to attract the naysayers.
On the other hand if somebody wrote a TR along the lines of "I toproped Classic Crack with the rope running through a sling, no biner. The sling is a bit melted now but I got up the thing" you might expect that someone would post up "You shouldn't run a load bearing rope through nylon cause it will cut the nylon and you will die" too.
I didn't pay enough attention to see if these Baker guys really were just dumb and lucky or if they were hyping relatively minor details in their TR up into a supreme mediocre epic chestbeat.
What exactly that was so bad that happened? They wore snowshoes, didn't take the 10 essentials, had bad weather and bad snow conditions?
