>I'm not understanding your point here, its the Youtube app. Why is it more on Roku ?

Because one nice feature of Roku is it will search for a program across all of the services. I can search for a movie and see it's $3.99 to rent on Amazon and $4.99 somewhere and free somewhere else. Maybe Google don't like being at the end of the list alphabetically, which might make sense for company that knows the drop off clickthrough rate.
