Hashicorp switches from open source MPL(Mozilla Public License) to BSL(Business Source License). The new license does not allow you to use Hashicorp products if you meet both of the following conditions:

- You are building a product that is competitive with HashiCorp.
- You embed or host Terraform in your product.

What exactly those conditions mean is open for interpretation and companies like Gruntwork are strongly opposed to this change(See relevant article here)
