I guess the nuance of my statement would be, trivially replaceable doesn't mean build a better product. Good examples of what I consider trivially replaceable would be services like Pingdom, DNS, S3, Cloud SQL since you can either easily build a "good enough" version, switch to another provider, or deploy your own from source. Good examples of services that are very hard to switch off of are things like Cloud Firestore or AWS Lamba.
