Where do they get the people who write these articles? It was confirmed quite awgile back that the Skulls are co-owned between Marvel and FOX. Basically Marvel can use the Skull race, but not specially named members such as the Super Skull or Shaper of Worlds for example. Those are owned by FOX.

It could be referencing more than Quill's 'fathers'. Let's not forget Thanos is Gamora's adoptive father.
