It isn't inherently bad, but it's usually a sign of more mass produced coffee. It's easier to roast coffee like that because it all tastes pretty much the same which is good if you need to make the same coffee for thousands of different locations. And some people enjoy the carbonic taste of coffee like that.

More lightly roasted coffees will have big differences in flavour that's not really possible to control for on a mass scale I don't think. Especially between origins and varieties.

it’s a sign that it’s a dark roast, which many mass produced coffees are. The third wave has tried to instill a culture of “nothing darker than a city roast” which I think has been harmful, as it marginalizes all dark roasts as cheap roasts, which isn’t the case.

That said, I think dark roasts age much less gracefully than a medium roast due to the oxygen exposure of oils, but I really love a full city roast for espresso.
