Google knows that the Open Source development process while nice and warm and fuzzy, can get in your way when you don't own the entire development of the project - especially if this is a product that can impact your revenue. Others can arbitrarily (sometimes with good reason) block your feature pushes and slow down your product releases. They did the right thing forking webkit, keeping Android/Chromium in-house, and are doing the right thing here. - IMHO.
