"You used AI!" is now being weaponized by project maintainers who don't want to accept contributions, regardless of how innocuous.

A large C++ emulator project was failing to build with a particular compiler with certain Werror's enabled. It came down to reordering a few members (that matters in C++) and using the universal initializer syntax in a few places. It was a +3-3 diff. I got lambasted. One notoriously hostile maintainer accused me of making AI slop. The others didn't understand why the order mattered and referred to it as "churn."
