If we go quite far back to the root of all this:
Perhaps he's not right about there not being any licensing, but the bolded bit is spot on.
I asked for a citation (and to reply to shandyman : Yes, I am ignoring you. Probably based on the fact that you're too Apple biased for your own good as most of my ignore list is based on that) and it was provided. Why the license "ran out" and why Apple feels they "need a license" other than as someone else pointed out, the use of the Youtube Trademark, we can argue long and wide.
The end result is the same though. Google will now be able to provide us with a much better experience, and at least issue App updates, something Apple didn't seem willing to do. Apple has a knack for releasing a "stock app" and then never updating it. Google is much more on the ball than that.
