This is as good as the Radiohead 01 10 album theory, the (confirmed) Tarantino movie and movie within a movie universes (also this), and the Tommy Westphall’s mind theory that connects almost every television series known to mankind. All Pixar movies are connected and occur in the same universe.

It’s surprisingly plausible, and utterly convincing.
Here’s something from the middle of that post.
In the beginning of Up, Carl is forced to give up his house to a corporation because they are expanding the city. Think on that. What corporation is guilty for polluting the earth and wiping out life in the distant future because of technology overreach?
Buy-n-Large (BNL), a corporation that runs just about everything by the time we get toWall-E. In the “History of BNL” commercial from the movie, we’re told that BNL has even taken over the world governments. Did you catch that this one corporation achieved global dominance?
Interestingly, this is the same organization alluded to in Toy Story 3:
Toy Story 3 (Buzz’s batteries)
In Finding Nemo, we have an entire population of sea creatures uniting to save a fish that was captured by humans. BNL shows up again in this universe via another news article that talks about a beautiful underwater world. In Finding Nemo, lines are being crossed. Humans are beginning to antagonize the increasingly networked and intelligent animals.
