first, they would only make it available in person, then you had to have a Macbook, then they said ok, Apple TV people can also see. And now it's "please, everyone show up and see it on YouTube!"

I don't see it as a maturity or ease of access or a win for YouTube as a streaming platform. I see it as a sign of Apple saying, "How can we make more people excited enough to buy our products now that the markets have matured and people are keeping their iPhones longer?"
