Nah, it's absolutely cultural, not about the money paid. Large accounts may make them more responsive quantitatively, but the qualitative lack of care is still there. Google is the opposite of Amazon, cares about its engineers, does not care about its customers. They operate on the model of letting a well engineered product (as determined by Google engineers alone) capture users, and this you can see through and through in the difference between GCP and AWS.

It has worked so far, but as soon as the day their technical quality starts to flag, they are probably as good as dead.
