The dirty reality is that software is tuned to constraints of a particular cloud provider. Talk to anyone who's turned a long-lived single-cloud production system into multi-cloud.
Example: How does AWS EKS provision control plane worker nodes? AWS CloudFormation. How do you manage security policies? AWS IAM. What kind of servers do you tune your software to run on? AWS EC2 of course.
Now let's say you wanna take advantage of this fancy "composing the solutions from separate clouds" thing. Let's say you like Azure's Blob Storage over AWS's S3. Guess what? You're now paying for cross-cloud latency! Both in time and in cost.
The devil is in the details.
