I don't know what you're talking about. By all accounts, GCP enterprise support is perfectly fine. Why do you think it isn't? Again, it's not consumer Gmail or YouTube accounts. Major companies wouldn't be signing contracts with them if they didn't.

And in what universe is revenue inconsequential? Profit comes whenever you want to stop investing in growing. There is zero reason to believe that Google will be unable to turn a profit off GCP whenever it decides to. Particularly given that it was building datacenters for Search before AWS even existed.
