This thread is fascinating - some weird malicious behavior in the... overlap of two privacy-centric operating systems

Please be aware that a Matrix / Element exploit is being used in the #grapheneos:matrix.org and #grapheneos-offtopic:matrix.org to impersonate GrapheneOS developers. They're adding special characters to the end of a nickname not shown in Matrix clients.

See grapheneos.org/#history for a basic summary of the history. GrapheneOS is the continuation of the original open source project. CopperheadOS is a closed source product based on our legacy code from the former sponsor of the project. They're unfortunately waging a war on us.

Thanks for the background! Was vaguely familiar with both projects but not this history.

GrapheneOS was formerly known as CopperheadOS (can see this from the many forks of our repositories on GitHub like github.com/CopperheadOS-T). Company was founded a year after it started and sponsored it. Ended up trying to take over the project, failed, and now tries to harm it...

They don't want the original open source project to exist, even though they almost entirely depend on our work. They massively ramped up the attacks on us after grapheneos.org/install/web was published providing a way to install GrapheneOS on a device via WebUSB in a web browser.
