I once complained on Twitter that I was having trouble with an EKS issue, and the product manager for EKS reached out to me directly, put me in contact with one of their engineers, and then they discovered an issue and rolled out a fix for it that day.
In a separate incident, I couldn't get GCP to read the verification data for a domain from their webmaster tools so I was unable to use the domain with GCP Cloud Run. I mentioned this on Twitter, and the product manager reached out to lecture me about how I shouldn't be using Cloud Run with domain mapping because that's in "preview". He then pointed me to another method to point a domain at cloud run, which it turned out was also in preview. All of this was because Google Webmaster Tools validated the domain but GCP wasn't able to get that information. I ended up cancelling the GCP project and just using AWS (as I should have from the start).
It's embedded deeply in Google's culture that they not only don't provide support, but they'll insult and gaslight the people asking for it.
