OpenTofu’s founders had a mission. Upset by HashiCorp licensing adjustments in August 2023 to its well-liked Terraform infrastructure-as-code software, OpenTofu set out to be the “open supply successor to the MPLv2-licensed Terraform,” additional promising that it “will likely be community-driven, neutral, layered and modular, and backward-compatible.”
Vastly promising, however terribly tough to drag off. So tough in reality, that OpenTofu could have illegally taken HashiCorp’s code to maintain tempo.
At the least, it’s laborious to keep away from that conclusion, perusing OpenTofu’s GitHub repositories and evaluating them to HashiCorp’s. Particularly, OpenTofu seems to have lifted Terraform code associated to a brand new eliminated block function first carried out in Terraform V1.7, which was launched beneath the Enterprise Software program License (BUSL) a number of months after the OpenTofu fork was created. The inform? OpenTofu took this BUSL-licensed HashiCorp code, eliminated the headers, and tried to as a substitute relicense it beneath the Mozilla Public License (MPL 2.0).
People, that’s not how open supply works. You’ll be able to disagree with a copyright holder’s alternative of license, however you don’t have the best to take another person’s code and rip-and-replace their license.
The hubris of youth
OpenTofu launched in September 2023 to a lot fanfare and “formal pledges” of help from greater than 140 organizations, amongst them Cloudflare, Harness, Oracle, and GitLab. In fact, the core maintainers largely got here from direct HashiCorp opponents (Spacelift, env0) that had constructed their companies on Terraform and had been upset by HashiCorp’s license change. Truthful sufficient.
By January, the mission was touting OpenTofu’s basic availability, even because it referred to as out soon-to-be-released options like client-side state encryption that Terraform didn’t have. Regardless of the optimistic begin, nonetheless, the crew quickly started to understand the problem of implementing the function. Safety is difficult. (Perhaps HashiCorp wasn’t dumb, in spite of everything.)
If that tempo of growth sounds too good to be true, coming from a unexpectedly assembled group of comparatively small corporations (and not one of the main cloud distributors), maybe it was. In any case, no matter one could take into consideration HashiCorp’s license change, the corporate has spent a decade constructing the product. The engineering muscle behind such an effort doesn’t spring to life in a number of months, regardless of the high-flying beliefs of founders.
Licensing magic
In Terraform V1.7, HashiCorp launched a significant new function: eliminated block automation, which lets Terraform higher handle useful resource deletion. Consider it as a config-driven strategy to terraform state rm. Nonetheless, the function itself, whereas cool, isn’t the purpose. The timing of that function is. Importantly, this function was launched in late November 2023 after HashiCorp switched to the BUSL. If somebody needed to make use of the eliminated block performance, they couldn’t get it beneath the MPL.
By late February, OpenTofu launched related performance to HashiCorp’s eliminated block automation. Not simply when it comes to what it does, but in addition when it comes to the code written to perform it. Check out these repositories and inform me in case you don’t see the identical factor:
Copyright regulation is sophisticated. I’m a lawyer by background, however I don’t observe and so can’t be thought of an excellent one. Perhaps it issues that OpenTofu appears to have deleted some feedback in a number of information. Perhaps it issues that they appear to have modified a line right here or there. Maybe one might credibly argue that OpenTofu has not, in reality, created spinoff works of Terraform’s BUSL-licensed code. Maybe.
Such an argument turns into much less persuasive, nonetheless, whenever you take a look at OpenTofu’s headers on the information. Right here’s the header that HashiCorp used on its eliminated block information:
// Copyright (c) HashiCorp, Inc.
// SPDX-License-Identifier: BUSL-1.1
Now right here’s the header that OpenTofu used:
// Copyright (c) 2023 HashiCorp, Inc.
// SPDX-License-Identifier: MPL-2.0
See the issue? OpenTofu acknowledges that it’s utilizing HashiCorp’s code however pretends the code in query was licensed beneath the MPL. Besides it wasn’t. Ever. All the code in query was launched after HashiCorp moved to BUSL for Terraform. At greatest, the OpenTofu group has engaged in wishful considering, desperately hoping it might retroactively make BUSL-licensed code magically grow to be MPL-licensed code. At worst, the OpenTofu builders deceitfully misappropriated HashiCorp’s mental property and tried to make it their very own.
No matter OpenTofu’s builders might imagine, this kind of conduct is the alternative of a constructive, “community-driven strategy” and undoubtedly doesn’t present “the worth of open supply,” because the Linux Basis press launch proclaims. It appears to be like rather a lot like a violation of HashiCorp’s mental property. It’s utterly honest for OpenTofu to disagree with HashiCorp’s license change and fork the mission; it’s utterly unlawful for OpenTofu or anybody else to take HashiCorp’s code and apply no matter license they like.
This seems like a failure of governance, amongst different issues. There’s no means that Cloudflare, Oracle, and different accountable corporations signed up for that type of group, however that appears to be what they’re getting.
