This is both a good thing and a bad thing, but Pulumi is way more flexible than Terraform. I wanted to have a cloud-provider-specific submodule that created resources (like EKS and GKE) that then exported output values (think kubeconfig), and then I wanted the parent module to pass those in as inputs to a cloud-provider-independent submodule. Terraform couldn't do it without needing to duplicate a ton of code, or without something heinous like Terragrunt (not sure it even would have worked.) Pulumi makes it trivial and in a language I like writing.

Additionally, our applications consume our cloud configuration (eg something that launches pods on heterogenous GPUs needs to know which clusters support which GPUs, our colo cluster has H100s but our Google cluster has A100s etc.) Writing in the same language in the same monorepo makes it very easy to share that state.
