Yeah right. Most developers wouldn't be able to even start writing a package manager, let alone maintain it for years as it becomes the most used one for a particular platform.
While that was true 10 years ago; I don't think it still holds. Google is more big generic enterprise now with all trouble innovating that comes with that. Hence, why they must buy to be able to push innovation forward. This is just part of the natural life cycle of a company as it gets big and successful.
