Even better: huge investment in their cloud and desire to get more people to switch. Response to best-of-class technology has always resulted in cries of lock-in. Opensourcing these things completely removes that risk.
Kubernetes: our container services are best; run your containers here, but if you don't want to anymore, run them anywhere using exactly the same api.
gRPC: our pub/sub is the best; run your rpc here, but if you don't want to anymore, run them anywhere using the same api.
tensorflow: our managed learning api is the best; run your learning here, but if you don't want to anymore, run it anywhere with the same api.
etc etc with dataflow and apache beam. These are best in class services, and except for bigquery (which has been a big driver of some of the big-name moves recently), they're using this model to take away the risk of transition.
