Your analogy is not fitting.

Placeholders are never meant to be part of the meal. They are there in the development stage when there needs to be something on the screen. They dont go trough the art department. Visual director wont review them. They are not representing the finalized game. They are there just as placeholders so people can see things work and not to need to look at wireframes when they work on the project. Often at parts of the game that has no quarantee to even be at the finalized game.

Generally graphics are one of the last things that is finalized in games. There is no point to use artists time for making placeholders, when they can spend that time doing something meaningfull.

In the end it does not matter if the placeholder is done by artists hand, is photoscanned from the doodles janitor made on toilet paper or if its done by AI. Hell, it could be pictures of spongebob fan art stolen from google search. It does not matter what people feel like is best and fastest way to get the texture, because its not representting the game and its not meant to be part if the finished product.

If you want to keep the food analogy, placeholders are the toothpicks holding your meatrolls in shape while they are in the oven. They wont end to your plate and if they do, somebody somewhere did a mistake.

Also i want to point out that not you nor i can say anything about overwhelming opinions. Clair Obscur for example has sold over 5 million copies. How big procentual part of those 5 million people you think has even read about the whole dispute, or put any meaningfull tough for the matter? Places like lemmy, steam reviews and comments on youtube videos are mostly from loud minorities that generally wont represent the whole fandom at all.
