Recently, Hashicorp announced a license change for its products, including Terraform. It’s been open source under an MPL v2 license for almost a decade; however now it’s moving under a BSL v1.1 license.
The Mozilla Public License 2.0 (MPL 2.0) and the Business Source License (BSL) are two different open-source software licenses with distinct goals and provisions.

Mozilla Public License (MPL) 2.0
- MPL 2.0 is considered a strong open-source license that allows for free and open distribution of the software. It is compatible with other major open-source licenses like the GNU General Public License (GPL) and the Apache License.
