I think that early days they were more opinionated. The design of the datastore is extremely google centric scale. Exposing it to end users was a matter of just "learn to use it, or not".

AppEngine had a lot of limitations, like the version of Java you could use, because they had to basically hack at the JVM to get it secure enough.

These days though, things like Cloud Functions, are effectively just simple containers and http endpoints. I could move them off to another provider with a days work.
