I was once going to give a talk on learning a specific programming language and framework at an event. My sample app was a "calorie counter / dieting app".

I was told at the last minute I needed to redo my example because it violates the code of conduct about discriminating against "people of size" and may be upsetting to people with "eating disorders"

I didn't even respond. I just stopped responding to their requests and didn't show up.

Codes of Conduct are used as blunt instruments now, and aren't useful.
