Yeah, it feels "not ND friendly" too. Totally breaks my reading flow.

I am the person addressed when someone says "you", not "yu". Why is that person changing how I'm addressed?

It's also confusing because it feels initially like it's some new Linux command or user, like "su".

ah, first sentence I thought yu was a typo. Second sentence I saw it I thought it might be a linux component of sorts. So it's not just a stylistic choice, it's actually harming my comprehension of what they're writing.
