My company runs AWS cloud all 20 of the non government regions as well, google cloud, and our own data centers around the world. Yeah certain regions (hello eu-north-1) are problemmatic, but we have work arounds for that. Terraform has been fine.

Why?
Because I worked at AWS for the last 8 years :)
Tbh, I don’t think it’s prohibited, but CloudFormation was the default choice.
You probably would have run into security issues with using terraform as each version would have to be vetted and any extensions you use
The Terraform AWS providers are maintained by AWS engineers, but the rest of the code will still need vetting.
