Clearly, Oracle must think there is some legal distinction between telling Terraform-as-a-service, and selling+distributing a product _containing_ Terraform that end users then use as Terraform-as-a-service.
Oracle Cloud's Resource Manager only supports Terraform versions up to 1.2.9 which is already quite old and of course open source. The license changes past the 1.6 versions don't affect the tool at all since it's using such an old version of TF.
Why Oracle Cloud isn't using Terraform version 1.5.7 which is still open source in Resource Manager is anyone's guess. Perhaps the tool isn't getting much attention recently?
Yeah this sounds like a very narrow use case shifting. That of moving your EBS ERP application to Oracle cloud from on premise.
I mean, people are doing that migration and it's exciting if they are actually using iac, but this can't represent large usage of Terraform.
I don't know much about Oracle's services so can't figure if this is a huge number of users, of a small subset of their clients.
