Was (mostly) joking. Point is, Moto likes releasing months old security updates. Seemingly without reason too, since the Droid models are up to March.
Some people complain about updates breaking the system ranging from reduced battery life to application errors + function losses.
Slower can be better for users who don't want to understand technical details.
I guess weird release intervals involve engineering teams who need to communicate with their hardware partners to certify drivers. Qualcomm is partially to blame. Project managers put all their efforts in flagships, and teams are only so big now since marketing budgets usually dwarf engineering's. If your product doesn't sell, then there is no next product. If nobody hears/knows about the product, then obviously it's not going to sell.
You have to understand process involves money unless the hardware was manufactured under the same label (see Samsung Exynos + other new proprietary chipsets).
For Google though, big picture is trying to eventually build a kernel that can update seemlessly through the mainline Linux kernel. Google is already a big Linux kernel contributor, and I suppose they were hoping some partners were going to hop on board. That never did quite occur as you see every hardware manufacturer out there branching out with their own proprietary chipsets. Now Google is willing to spend more money in developing hardware to make that happen.
