The popular Hashicorp digital infrastructure provisioning tool Terraform, which was released with the Mozilla Public License has been re-licensed by Hashicorp using the Business Source License, which is a non-free, non-open source license.
In response individual and corporate users of Terraform have established the OpenTF Foundation, as part of the Linux Foundation.
And have announced plans to release a fork, which is expected to be published to their GitHub project in the next few weeks.
I’ll be switching from Terraform when OpenTF becomes available.
