But it isn’t about the plagiarism. It’s confirmation that the institution only cares about empty platitudes while not really doing anything else to help their students. And if they’re not helpful, why does their job exist?
The futility of the whole situation has resulted in a culture of ceremony around the devastation as a way to cope. Now that people have violated the coping ceremony, we're mad at them. But why? Because we are powerful enough to at least scold them in an attempt to preserve the coping ceremony. But they're not the ones shooting people. They're not the ones directing policy that causes mass shootings.
Instead, we need to direct all that anger to changing the situation such that they never are put in a position of writing letters about shotting victims. Instead of smugly stating they are worthless people because their jobs can be replaced by a chatbot, we should question why it is the case that someone's job is to write condolence letters after shootings. Why aren't we mad that's an acceptable job function in the US? The solution students are looking for is not more empathy toward shooting victims, it's fewer shooting victims in the first place!
You're kind of missing the point:
1. Institutional practices/beliefs about plagiarism will influence its behavior in other areas.
2. "Empty platitudes," are often necessary, as a social lubricant. People aren't robots. Sometimes you can't do anything, but also you can't say nothing.
3. I very much doubt the university administration only exists to send out these messages, so you can't reasonably question if their job should exist based on this narrow episode.
