The code in question was originally licensed under MPL, not BSL. OpenTofu announces upcoming pre-release version. ## Content The OpenTofu project recently received a Cease and Desist letter from HashiCorp, accusing them of copyright infringement. However, OpenTofu firmly denies these allegations and provides evidence to support their claim. They assert that the code in question was actually copied over from an older version by a HashiCorp engineer. OpenTofu emphasizes that they have always adhered to proper licensing and that the code in question was originally licensed under the MPL (Mozilla Public License), not the BSL (Business Source License). They further highlight their progress in development and announce an upcoming pre-release version of OpenTofu. Despite the legal dispute, OpenTofu remains committed to their mission of open-source software and looks forward to resolving the issue amicably. ## Similar posts on daily.dev - [Don’t just attend KubeCon \+ CloudNativeCon, Merge Forward your experience\!](https://daily.dev/posts/don-t-just-attend-kubecon-cloudnativecon-merge-forward-your-experience--l0rpp73x8) · CNCF · 1 upvotes · 0 comments - [Announcing H2 2026 KCDs](https://daily.dev/posts/announcing-h2-2026-kcds-m96goajm1) · CNCF · 1 upvotes · 0 comments - [Two months of Open Community Groups](https://daily.dev/posts/two-months-of-open-community-groups-asf52zhbs) · CNCF · 0 upvotes · 0 comments - [CNCF Unveils Schedule for KubeCon \+ CloudNativeCon Europe 2026](https://daily.dev/posts/cncf-unveils-schedule-for-kubecon-cloudnativecon-europe-2026-ikhcoa5cb) · CNCF · 2 upvotes · 0 comments - [CNCF Debuts KubeCon \+ CloudNativeCon Japan 2026 Schedule](https://daily.dev/posts/cncf-debuts-kubecon-cloudnativecon-japan-2026-schedule-xp5pyudub) · CNCF · 1 upvotes · 0 comments --- Tags: [#open-source](https://daily.dev/tags/open-source) [View this post on daily.dev](https://daily.dev/posts/opentofu-s-response-to-hashicorp-s-cease-and-desist-letter-rxdpl8p9q) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"OpenTofu's Response to HashiCorp's Cease and Desist Letter","url":"https://daily.dev/posts/opentofu-s-response-to-hashicorp-s-cease-and-desist-letter-rxdpl8p9q","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/opentofu-s-response-to-hashicorp-s-cease-and-desist-letter-rxdpl8p9q"},"datePublished":"2024-04-12T18:12:23.509Z","dateModified":"2024-04-12T18:12:21.140Z","description":"OpenTofu denies copyright infringement allegations and provides evidence.
