She's not saying they're evil! She's just presenting a data point, and then some further advice on screening once you get a first meeting. The people arguing about specific entries on the list are missing the point.
I agree that "zombies" is good writing but suboptimal reporting, in the same sense as maybe Ron Conway really isn't investing, but if he's not taking spurious first meetings with company operators, he's not "walking among us" and thus doesn't qualify as a zombie.
