The meatiest part of the wing is actually meat cut from the breast, so I would consider them white meat. If I asked for all white meat at a fried chicken place, it wouldn't surprise me to get a mix of breasts and wings, but it would surprise me to get just wings. If I asked for all dark meat, I'd be annoyed if that included wings.
I can't say if they do it this way at Popeyes (there isn't one anywhere near me), but at KFC they have a 1-piece meal with sides that they specifically say is one breast (presumably to avoid the prospect of getting a wing or a drumstick as your one piece of chicken). When I order one of those types of meals, I usually get a 2-piece and specify that I want a thigh and a drumstick, since I prefer dark meat but don't really want either two thighs (too much) or two drumsticks (not enough).
I also know that a lot of fast food restaurants in general are franchised, so I wouldn't necessarily judge an entire chain on a single location, if the issue was primarily the service and not the food itself.
