Hetzner doesn't even have an RDS service. I've heard rumors for years but they haven't done it. Also, while I agree that leaning too much on the cloud leads to lock-in - this is an abstract concept that needs to be guarded against when managing technology, always, anyway - and vendor-driven hellish architectures, "vanilla cloud" offers other conveniences other than compute, bucket, storage managed and load balancers, like IAM, good CLIs, secrets management, etc. Only Scaleway or OVH seem to be timidly developing what I would consider "vanilla cloud".
