To provide some additional context and clarifying points that I see in the lower comments: >> Regarding financial incentives: Google is an insanely large organization, and the priorities and KPIs of one org (Chrome) largely don't impact another org (YouTube). Additionally, YouTube is a regarded as a red-headed step-child within Google and is generally outside of the general interactions with other orgs. That's based on years of working on that fine line. >> Regarding Useragent Targeting: The targeting scheme treats the useragent as a string, rather than a distinct value that the useragent is set to. Chrome is likely to hit this bug as much as any other browser vendor.
