There's a difference between someone with a Gmail account who added a card to GCP and spun up a VM, and a business with a business account. Google support isn't there for the former, but there's plenty of it for the latter.
That may be true, but many people won't even try it to find out because "Google" itself is synonymous with "customer service black hole". They should have given their cloud product a name other than "Google", similar to how Microsoft named their offering "Azure" and not "Microsoft Cloud" - if Microsoft (the name) has bad rep, they can just drop that moniker to preserve their cloud offering as simply "Azure".
