On April 3rd, we received a Cease and Desist letter from HashiCorp regarding our implementation of the “removed” block in OpenTofu, claiming copyright infringement on the part of one of our core developers. We were also made aware of an article posted that same day with the same accusations. We have investigated these claims and are publishing the C&D letter, our response and the source code origin document resulting from our investigation.
The OpenTofu team vehemently disagrees with any suggestion that it misappropriated, mis-sourced, or otherwise misused HashiCorp’s BSL code. All such statements have zero basis in facts.
HashiCorp has made claims of copyright infringement in a cease & desist letter. These claims are completely unsubstantiated.
The code in question can be clearly shown to have been copied from older code under the MPL-2.0 license. HashiCorp seems to have copied the same code itself when they implemented their version of this feature. All of this is easily visible in our detailed SCO analysis, as well as their own comments which indicate this.

Conclusion
Despite these events, we have managed to carry out significant development on OpenTofu 1.7, including state encryption, “for_each” implementation for “import” blocks, as well as the all-new provider-defined functions supported by the recently released provider plugin protocol.
On that note, we will be releasing a new pre-release version next week, and we are eager to gather feedback from the community.

This is unrelated to this topic exactly, but I don’t know what OpenTofu is nor what it is for, so I looked at the FAQ.
What is OpenTofu?
OpenTofu is a Terraform fork, created as an initiative of Gruntwork, Spacelift, Harness, Env0, Scalr, and others, in response to HashiCorp’s switch from an open-source license to the BUSL. The initiative has many supporters, all of whom are listed here.
This is practically a meme…I have no idea what all of these are (coming from my area of expertise).
I’ve run into this problem a lot with many open source projects. It’s sometimes really hard to find out what the hell something actually does based on just the project’s own pages. It took a while for eg. join-lemmy.org to actually describe what Lemmy is, for example, instead of just going on about it being open source and secure and federated and blah.
That’s just a classic issue with most tech people: they either forget or don’t know how to adjust their speech for a different audience than themselves. Often they don’t even comprehend just how much “common knowledge” isn’t actually common outside their social spaces.
Then there’s some that are deliberately refusing to help uninformed people understand, or are even outright hostile to them.
Yeah I really don’t know where hostility against newbies (actual or perceived) comes from in nerd circles. It’s been like this for as long as I can remember, and I’ve been eg. using Linux from the late 90’s and fucking around on the Internet for over 30 years now. At least things are way better than they used to be, but it’s still sometimes a bit of a bumpy ride
Often they don’t even comprehend just how much “common knowledge” isn’t actually common outside their social spaces.
I see this literally all the time in the documentation that my coworkers write. I think it’s kinda wild. Like do people really not have this self awareness? Or am I just as bad without realizing it? That’s what scares me.
I had the exact same question, did the exact same thing, and had the exact same response. EVERYONE does this, it’s infuriating. If you’re going to have a public-facing info page about your project or product, you need to assume that people know NOTHING about it.
Terraform and OpenTofu are great tools for building virtual infrastructure, e.g. using AWS API calls to spin up AWS virtual machines and provision them with networks and security relationships and stuff like that–in an automated, repeatable way. They are generalized tools for deploying and modifying infrastructure, even if it’s not in the cloud (there are many tools in these frameworks that apply to self-hosted setups).
The rest of the words after “Terraform fork” are just the names of companies that decided to help OpenTofu, and are not especially helpful in understanding what it is or what it’s used for.
Terraform is an infrastructure-as-code software tool created by HashiCorp. Users define and provide data center infrastructure using a declarative configuration language known as HashiCorp Configuration Language (HCL), or optionally JSON.[3] —Wikipedia
It makes more sense when I dug into it more deeply, but still—gave me a chuckle.
I thought they were random names created for the funni.
detailed SCO analysis
groklaw ptsd flashback
I saw that too and thought “here we go again”, but in this case it seems SCO stands for Source Code Origin.
Pretty shitty attempt on Hashicorp’s part. Come to think of it, are Hashicorp themselves in the legal clear for grabbing code from an incompatible licence?
Well, I’m sure they are worried about their new deal with IBM that they’ve obviously been working on for a while.
Yep, the timing lines up. As part of the buyout offer, they probably had to demonstrate an effort to cripple the open source fork of the thing IBM wants to buy.
We’re in the age of corporate corruption and they’re public – Probably would get sued by investors for not ruthlessly hamstringing all stakeholders in the space. Fuck this place.
I don’t think OpenTofu is accusing them of taking any code from an incompatible license. Just saying that both parties did the same thing.
IIUC all past Terraform code was copyright assigned via a CLA. This is what allowed them to re-license in the first place. So even if the previous code was offered under an incompatible license they own the copyright so it doesn’t matter.
I’m not saying OpenTofu is doing any accusing, but I am. I was thinking an original author had the sole right to relicense code but I guess they found some legally plausible way to get it done. I wonder if the author was an OpenTofu employee.
See https://en.wikipedia.org/wiki/Contributor_License_Agreement#Relicensing_controversy for a basic overview.
Lots of projects will have a CLA that basically says “You assign copyright of your work to us” or some sort of unlimited rights grant to the project. So depending on the exact CLA the author may completely transfer ownership of the patch to the project, maintain ownership but grant the project a licence to do basically anything with it (including re-licencing) or for less strong CLAs just confirm that you license the code under the project license.
Thanks for the link, I forgot about CLAs. Interesting - this kind of thing seems to be controversial but common.
They are a powerful tool. They are controversial because they can be used for good and evil. For example even some FSF projects require copyright requirement: https://www.gnu.org/licenses/why-assign.en.html. (It used to be all projects, but many have them have switched to DCO, example glibc)
But of course it also means that an organization can take code in a GPL project and start disturbing closed-source versions.
