"BUT EVERYONE ELSE IS DOING IT!!!!" is not an excuse you'd accept from a child, so why does it become an acceptable defence in politics and journalism?
Your comment seemed quite sarcastic, and looked to be trying to equivocate responsibility. Not that I'm above using sarcasm myself, obviously.
The fact is, that in this instance, a Murdoch owned media company is clearly distorting the truth to further a political agenda. So in this instance, it is perfectly reasonable to criticise Murdoch in particular, without having to resort to qualifications.
It didn't sound like a defense, but an observation that, sadly, this is common behavior.
I also suspect it was a sly reference to some of the comments on HN, too.
