I'm not disputing that -- the approach of the issue OP was what irked me.
Imagine being at work in a professional job and filing a bug like that to a coworker. Totally inappropriate.
Frankly, it's usually just gatekeeping (or just being threatened) hiding behind some moral system they just assume you should share with them.
"There is no RETURN, SHIFT...", "Too many F keys". They are confusing a typeface with trying to replicate the keyboard keys.
The arrows are not the cursor keys, but based on the ESC key.
They are right about the @ character though, it looks quite wonky.
