Microsoft has access to a Youtube API

I may be wrong, and feel free to prove me wrong if I am, but to my knowledge, the Youtube API is open to everyone that wants it here. What Microsoft wants is specific metadata that Google would like to keep exclusive to itself. I think Google should either open up that metadata, even if it has a licensing fee, or collaborate with Microsoft, in my opinion, but nothing is stopping Microsoft from making a Youtube app that works just fine.
