Remember, friends: thanks to X's creator program, people like this loser farm rage over things that don't exist to pay the rent.
The orange triangle is an option in the accessibility menu that you can turn off, and to make it appear, you have to press R3. He is literally trying to make this look as bad as possible to make fun of it so people rage at Insomniac or respond by calling him out —either way, he makes money.
As an added bonus, you can see people in the comments making fun of accessibility. The more this happens, the more people are using accessibility to bash games.
The BEST thing you can do is block; it tells the algorithm that his content is not worth reposting, and the more people who block, the fewer people will see his content, and then he and the other rage farmers will have to figure out a productive way to make a living instead of making up reasons to shit on other people's creations.
