From a technical standpoint, "0gomovie" is a network of domains designed to circumvent copyright enforcement (a feature often called "Whac-A-Mole" infrastructure).
He is the last of the physical-media scavengers, living in a cloud-based world. While his children stream 4K effortlessly to an iPad, the 0gomovie Dad is troubleshooting a .mkv file with DTS audio that refuses to play through his TV speakers. He spends forty-five minutes finding the right codec. He considers this a victory.
There is a specific dopamine hit that comes from clicking "Download" on a CAM version of a movie that is still in theaters. He does not care that a shadow walks across the screen every seventeen minutes. He does not care that the audio sounds like it was recorded inside a popcorn bucket. He cares that he won .
A critical "feature" of interacting with sites like 0gomovie is the security risk.
