Archaelpteryx is not a bird. It's a dinosaur very closely related to the dinosaurs that gave rise to birds. Things like a keeled breastbone, a pygostyle, and others only evolved in the dinosaurs which are birds.
Not hard to understand. As usual, AiG got it wrong. There is no loss of information for teeth in birds. Indeed, teeth can be induced to form in them; they still have the genes for teeth. Some birds still have vestigial teeth.
Paleognath birds are a group of flightless birds that still retain dental structures. Despite their inability to fly, these birds have teeth that aid in their feeding habits. Ostriches, emus, and kiwis are notable examples of paleognath birds. Their dentition varies in terms of tooth size, shape, and number, but they all possess teeth that assist in the breakdown and digestion of their food.

That information isn't expressed now, because new genes suppress them. Added information.
As usual, ignorance is what tripped them up.
