"YouTube has already invested more than $60 million into its Content ID system" That actually seems low to me, given we're talking about numbers (revenue, users) in the billions.
I was surprised when the best way to watch UFC 229 (PPV) was simply typing it into YouTube and watching full HD quality. YouTube won't do anything unless government action forces them to.

edit: By "robust", I actually mean, "a bit overly proactive", in that the system seems to be efficient in its detection, but the system's design seems unavoidably vulnerable to false positives.
