Did you bother taking 30 seconds to research? Because there is article after article.

OceanGate CEO Stockton Rush — who was one of five passengers that died on the Titan’s journey to the shipwreck — once bragged that his submersible invention operated with simple objects like the video game controller.

Sounds like you didn't bother to do even 10 seconds of research.

A now viral CBS report from November 2022 had OceanGate CEO Stockton Rush giving a tour of the company's Titan submersible, where he showed a Logitech gamepad and said: "We run the whole thing with this game controller."

I find it curious the hyper focus on that part of the post when the real point was the curious connection between James Cameron's connection to Mr. Titanic (superhero of France?). He gives an ABC interview on 6/22, but does not mention anything about his friend of 25 years dying aboard.
