You, humanitec, and env0 should start a community fork of pre-BSL Terraform and donate it to the CNCF.

Massdriver would contribute here.

I believe it's a bit too early to make this call but based on the experience of interacting with Terraform the binary it would be absolutely amazing for the community if Terraform could be turned into a library that can become a building block for higher level services.

I really hope this happens.

I don't know the details of BSL, but can HashiCorp now require compensation/$$$ from Spacelift, Scalr, Env0, etc? In that case, these products can be forced to offer similar pricing as Terraform Cloud.

IANAL but I believe the BSL restrictions only apply to new upstream code versions. All HashiCorp repos can and always will be usable under MPL as they were up until the moment immediately before the license change.

In other words: if you hard fork now, you don't need to pay.
