Funny panel, but to be honest I think the message is kind of misplaced. With something like video games opinions are always going to be divided, especially with the lines increasingly drawn between casuals and serious gamers. Also, I think a lot of it is also that people expect consistincy, a lot of attacks on journalists come from someone winding up in the position of "game journalist" for basically being a nerd's nerd, a serious gamer who knows pretty much everything about the medium. When you see a gradual shift in tone from a reviewer being critical of casual games, directed at the masses, to being more accepting of the kinds of games the casuals play and the industry wants to make, that's when the problems usually happen. When a reviewer has to start defending games based on arguements like "judging them on their own merits, right now" his credibility goes out the door, especially when he's supposed to be there due to their lengthy knowlege of the media and their abillity to put things into perspective. If your an expert who is accepted as one because you can compare a game now to one 10 years beforehand and find it lacking from a design standpoint (for example) and then refuse to do that (quite probably because of industry/publisher/advertising pressure) the big question is what point your expertise plays. You could literally just plug in a video game for a hobo and get the same kind of "on it's own merits" review.
I'll also say that game reviewers generally get paid by a publisher, whether it's physical media or digital, not based on a percentage of ad hits. Now granted, by not making any money a publisher can go down leading to lack of employment, but that's very indirect. I'll also say that if people want to deal with ad blockers on their sites and encourage people not to use them, they need to be more careful about what ads they accept and how obnoxious they happen to be. If I come to your website I do not want to see 10 other pages open at the same time, or some animated figure scroll around the screen, obstructing my view, until I acknowlege it, or some obnoxious voiceover shooting out from a video in the corner. The problem with online ads is they tend to be utterly obnoxious, and the guys running sites rarely bother to worry about anything other than how much they will be paid for the ad. Basically when the ads themselves chill out and stay out of my way, I might consider not running software to shut them off... Oh yes, and then there is the whole bloody issues of tracking cookies and crap. Even with decent online security/ad blocking (though by no means perfect obviously) I routinely pull hundreds of tracking programs, cookies, and other crap out of my system which cumulatively do slow it down when it gets to a point. Not to mention that I don't really care for the idea that some advertiser wants to "track my web surfing habits" or whatever the heck.
Let me put it another way, even if I literally believed game journalists would starve due to blocking ads, I wouldn't really care, because you'd pretty much be argueing they make their living by being professionally obnoxious. Starvation might actually be considered too good for the people who create and spam a lot of these ads.
