I think it is something else. If you think about it, humans often write about correcting errors done by others. Refactoring code, fixing bugs and write code more efficient. I guess it triggers other paths in the model, if we write that someone else did it. It is not about pleasing but our constant desire to improve things.

If we tell it a rival LLM wrote the code it will be extra critical to tap into of its capitalist streak to crush the competition?
