In all honesty, we don't know whether Teach absorbed or ate the Gura Gura no Mi. What we do know is that if you eat two DF's you explode and die. We also know that Blackbeard has a Devil Fruit that allows him to absorb anything, including non-tangible attacks like fire and lightning. The only reasonable theory we can then produce from these two pieces of information is that Blackbeard directly absorbed the powers of the Gura Gura no Mi without eating it. Sure, he could be anomaly, but it's more likely that no one can eat two DF's than one person in the entire world can.
