How Misusing Git Commands Triggered an International Legal Nightmare

Yesterday a colleague posted a link to https://github.com/langgenius/dify/pull/16819 in a work chat, claiming the submitted PR had already attracted a lawyer's letter. The author was surprised because they assumed contributing to a well‑known open‑source project like Dify would not result in legal action.

Examining the PR revealed its massive scope: 95 commits affecting 68 files and altering 1968 lines of code. The changes included a bold replacement of Dify’s official logo with a custom version, apparently intended to re‑brand the project for a fundraising push.

The PR author also left a comment demanding a merge, which attracted community feedback. After a short discussion, the Dify maintainers posted the official lawyer’s letter, confirming the violation.

Instead of a simple apology, the offending party responded with a mass email full of insults, a reaction the author likens to a similar incident involving Tencent Cloud.

Further analysis shows that the detailed steps in the project's documentation would have prevented exposure if followed correctly. The root cause appears to be the operator’s unfamiliarity with Git commands, leading to the disastrous PR.

Reviewing Dify’s license reveals it permits commercial use provided the original logo is not removed. The PR’s removal of the logo directly violated copyright law.

The incident underscores that open source is not a free‑for‑all; sharing does not grant the right to impersonate or strip original branding. The author recommends reading "The Cathedral and the Bazaar" and "Hackers & Painters" to better understand open‑source ethics and intellectual‑property respect.
