This is much bigger than any "google killing products" issue. Azure got a lot of ways to push itself in, and reaps a lot of possible clients by being first party windows solution for companies that have a lot of windows stack.

AWS has the first mover advantage and enormous brand penetration - it's literally the "you can't get fired for choosing AWS" (instead your company might fold due to AWS bills, but you'll be clean).

Meanwhile Google seems to be much less known in cloud infrastructure space - people think of Google Apps/Workspaces, not GCP, and they seemed to have serious problem getting to clients. I know I was quite surprised by the available stuff and low prices when I did my first project on GCP back in 2016, and generally I've been pleasantly surprised except by their horrible billing support (Google can't into actually getting paid?)

They are in this funny situation where they constantly seem to be lacking fully blown virtuous cycle of adopters and supporting companies, despite having some of the best options on the market - but I think the real issue is that they are neither the first mover (AWS) nor "canonical windows source" as with Azure.
