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.
MuhammadFree🇵🇸@GrapheneOS Very sorry to hear that. Could you explain what you mean with "failed takeover attempt" or give references? Thanks.
