GrapheneOSGrapheneOS started in 2014 and was originally named CopperheadOS. In late 2015, the Copperhead company was founded which was meant to support the project. Copperhead didn't create CopperheadOS and didn't own or control it. Copperhead made a failed takeover attempt on it in 2018.
GrapheneOS still has the original CopperheadOS repositories on GitHub. Copperhead seized a bunch of the project's infrastructure and accounts. They created a closed source fork of GrapheneOS called CopperheadOS after the split which was not the same CopperheadOS as the original.
Copperhead remained entirely dependent on GrapheneOS and had to keep forking our code for each major Android update. Despite depending on GrapheneOS, they waged a war against it trying to destroy the project and attempting to ruin the lives of our team, especially our founder.
Copperhead heavily pushed the false narrative that they created the project and that we created a fork in 2018 which absolutely isn't true. Their claims fell apart in their legal attacks on GrapheneOS and we wiped out their closed source fork by forbidding them using our code.
Jerome@GrapheneOS Did the court publish their decision? They do in many countries. If they did, you can use that as evidence to correct the Wikipedia articles.
