I doubt Amazon or Google wants to take ownership of anything that is not DIY-centric or must be sold/installed/managed by 3rd party integrators. they can easily replicate the C4 (or any automation) functionality in time for a fraction of the price to end-users. Hell - there is nothing in my house I cannot do (or need) with a Harmony Pro and Alexa. Big automation platforms are slowly dying and not coming back.
