Disney bought Pixar and Pixar made WALL-E. Disney bought Marvel and Marvel made GotG.
OR, did you mean that since GotG pre-existed the buy-out in comic book form, it differs from WALL-E which was created new and in-house? But even then, Disney seems to treat Stitch, and Wreck-it-Ralph, and Frozen, and Brave, and Coco, and Moana pretty well and they were all made-up in-house. So, still, a point made from bad analysis of data. Hope your life doesn't depend on you doing systems analysis.
Your hate is clouding your mind. For your own sanity, take a break.
