The description of the BSL license as “faux-source” I ran across in this article about the saga of Terraform is perfect. It also speaks well about the the capability of OpenTofu as a replacement for Terraform. I haven’t done much with it recently, but early signs were very encouraging.
It’s very unclear what IBM’s intention is with the aquisition of Terraform. Maybe they will even change the license back and remerge with OpenTofu? Stranger things have happened…
