In the middle of a proper business row right now with Amazon refusing to sell some of Google's products as well as fucking about with how Youtube worked on Echo. Google have responded by pulling Youtube from Amazon devices (gone from Echo and from January 1st on Fire TV) to try and force Amazon's hands.
Who wins? Unsure but right now all they're really doing is hurting customers.
