I am not defending YouTube redirecting a UA it hadn’t seen to download chrome when that UA explicitly went to /new for the new experience. I don’t know what happened there, and if I did I probably couldn’t say. I am defending using the UA to tier responses based on the principle that it lowers the latency before the page is useful to the user, and I don’t see how that is a sinister practice.
