I think reading “u” takes longer than reading “you”. With “u”, I have to pause for a moment and think “that’s not a normal word; I wonder if they meant to type ‘i’ instead (and just hit a little left of target)?” and then maybe read the passage twice to see which is more likely. I don’t think it’s quite as much a contradiction. (It still could be more gruff than needed.)
