As a counterpoint, we've had no issues with GCP and have found it to be a better product than the alternatives for what we want. We have an account manager, have received lots of support from Google in setting up, have been able to trial products in closed alpha before release, and haven't been hit by any meaningful deprecations. We also have a contract with SLAs that do not let Google arbitrarily cut us off. Obviously they still could, but at least it would be in explicit violation of a contract.
Also something that is rarely cited as a plus point: we are not a Google competitor, and one of our major partners considered it a significant benefit of using us that we did not host on Amazon services. There are an increasing number of businesses who may see some value in not hosting on AWS.
