Who reads a contemporary RPG guidebook and gets offended by being told that something they like in their games - non-encounter, non-action driving scenes with gate guards - aren't fun? If you disagree, note the disagreement and move on!
True, I'm not offended by it. I do think it's terrible advice, and certainly less excusable than what Gygax wrote all those years ago before the hobby had even developed. And, I think Gygax gave some terrible advice in his time, too.
What I don't get is the complaints that it's "terrible advice." What does it matter to anyone that some stranger - whose GMing practice is being shaped by the 4e DMG - might be running games in a different style? And if those strangers really want to run exploration-heavy games with free-floating colour, I'm sure they'll find there way there regardless of what they might have read in the 4e DMG.
It would be terrible advice if it was prone to produce games that were actually inferior in some way. But where's the evidence for that? I haven't seen any.
Because it will produce inferior games if followed for many groups. It would for my group. It would for others in this thread. While most of us would eventually ignore it, if I had only the DMG to go on, it'd slow down my fun to start out with. It'd actively hamper my fun.
Luckily for me, I started with my older brother getting me into the game. And, luckily for me, I'm pretty intelligent and charismatic (and good looking... I could go on), so when I started GMing myself, I got better pretty quickly (and am probably slowly improving to this day).
However, if I only had the DMG for advice to go on, and I followed the advice that he gives there, I'd be missing out on a type of fun I find fundamentally improves the game for my group. So, in my mind, if advice on Fun actively hampers the Fun I'll be having, it's terrible advice. The logic seems simple to me.
While the play style the advice will produce may work great for a different group, that matters little to giving advice on Fun to the masses. Any sort of objective value judgement on Fun is probably terrible advice, especially if it's declaring a particular common play style better than other common play styles in the hobby. And, not just better, but those other play styles "not fun" in general.
Why you can't see that as terrible advice is beyond me. He's giving advice that would actively hurt Fun for a lot of people if they followed it (passively hurting it might be bad, but actively hurting it makes it terrible, in my opinion). To me, the quality advice of advice should be judged on "what would happen if I followed this?" and not "how easy is it to ignore this?" As always, play what you like
