I am sorry to hear that, but I can assure you it's not the case. I'm an engineer on a newer (and therefore smaller) AWS service, and I help investigate customer complaints, from customers of all sizes, all the time. I'll also note that not only do we handle cases that come in via our paid support, we also do deep dives for customers who post to our service's forums and indicate issues.
On the other hand, Google takes my Android app off the play store with next to zero details on the reason why and I have next to zero methods to contact them. The only way I was able to get my app back was to remove features via trial and error to determine what part was infringing. Why would i partner with Google again for hosting?
Play is a low margin business per "customer" compared to cloud. This has direct impact on the type of support you can expect.
I mean, when people think of AWS services, do "service and stability" really come to mind? IME it's impossible to reach a person unless you're a multi-million-dollar org, and Amazon itself tells customers that AWS services can go down at any time and it's up to the customer to architect the application to deal with it.
If I had to peg a reason AWS gets treated differently in the marketplace, I think it's probably some combination of a) AWS was first to market, and b) AWS revenue seems materially important to Amazon, while Google Compute revenue is a rounding error to Alphabet. Therefore, Amazon has a lot more incentive to keep, maintain, and grow AWS.
