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).
