Signal boosting this for truth; I've used "Magicpunk" to describe Eberron in the past, particularly to folks whom I know are cyberpunk fans. Which is why this comment:
...is absolutely right about what it means to be "punk" (that is, commentary about modern culture) but largely misses the mark about Eberron itself. It's subtle, and it may not have even been intentional in all places (though given the sources of inspiration, I'm skeptical about that), but Eberron as a campaign setting is a lot more subversive than people tend to give it credit for.
YMMV of course; every DM's game is going to be quite a bit different, emphasize different aspects of the setting, etc. But the punk aesthetic is absolutely the reason my players and I took to the setting as much as we did.
I was more specifically talking about Steampunk, which obviously leans on Victorian traditions, which Eberron isn't quite as interested in. Feminism, particularly, is a major element of Steampunk, but, is largely a non-issue in Eberron. Or, rather an absent issue. A female PC is (hopefully) treated exactly the same as a male PC at the gaming table, so, the subversive elements (such as Doctor Who giving us a female (and saurian) Sherlock Holmes.

Now, as far as Eberron being subversive, actually, I would agree. For one, it is hugely subversive of D&D itself. It takes a lot of the D&D tropes and turns them on their heads - humanoids as integrated members of society, for example. Evil scheming Mob Gnomes. So on and so forth. So, yeah, I'd agree with the idea that Eberron is a punk setting. Magipunk? ((I do LOVE Khyberpunk)) Just not Steampunk.
