Sounds like Google didn’t want Roku streaming YouTube videos in an unofficial way. Dave Zatz posted this morning that the channel wasn’t available for people that didn’t already have it added. This isn’t anything new for Google and YouTube. There use to be a public API that YouTube stopped using to make companies work with them to get content. It’s mentioned in the comments on ZatzNotFunny that the Popcorn Hour had this issue a few years ago. I’m sure they are working together to get YouTube back.
