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?
