Everytime I see something like this rolling out of Google, all I can think is "if only this was a real project, and not yet-another-Google-shop-project". And no, that's not fair towards the people who make it, but then the entire thing is clearly marked as copyright Google, not copyright the people who deserve the credit, so Google doesn't even want me to think of this as something cool made by cool people, but another library pumped out by Google for the betterment of a market position.
What's bothering you?
Google apparently allows people to make awesome stuff during business time, and then released it under Apache License 2.0, which seems to be a pretty permissive license (https://github.com/google/songbird/blob/master/LICENSE)
It may not get the attention it deserves, but no project is guaranteed to have a maintainer-for-life.
Mostly the part where it stays a Google project, and despite Apache licenses, no one can contribute without signing a CLA that discriminates against any developer without a phone or a permanent address. "The lawyers insisted" means I don't like the way you think you're releasing useful code into the world when you're really presenting something you locked down so hard people need to give you their direct personal information before you let them help make it better (Facebook does the same thing, which is why I don't contribute to their projects despite loving quite a few of them and using them daily).
