I used to work in an small org running on GCP, and the most infuriating thing was they would very often deprecate services in favor of new ones. Almost every year we had to spend a few months migrating to a V2 of a service. That's months of resources being spent on work that the company didn't really need to do.
This was a couple of years ago, I don't know if they are better at it now. But a quick search shows this looks like it is still a thing.
