people who use generative AI tend to hide the fact they used it
How do you know that?
It is not the impression I got.
I see people reporting ai usage that is not even gen ai usage as ai. I see people bragging how they vibe coded a thing. But I do not rember seeing someone being dishonest about it.
You also need to consider the context. Is it a company or a hobby game dev. The company risks negative public image and even a ban from platforms. And the hobby dev has not much reason to lie about it.
Do you have any examples for systematic intentional ai usage hiding? What were the circumstances?
I remember one company having accidentally left in a prototype image in a game and there was backlash about even that. A company "lying" about these things is news.
