Just blogged about this here[0] but at least they're not doing the usual canned PR response surrounding this.

Folks are already building on top of it:

thedavidweng/gork-build[1] — rebrand grok→"gork", stripped vendor telemetry, opt-out-only data retention, blocks x.ai auto-update. A "VSCodium-style privacy fork."

DigiGoon/digi-grok-build[2] — "dgrok" multi-provider CLI, builds from source instead of x.ai CDN.

victor-software-house/open-grok[3] — "opened to every provider."

LukaMucko/grok-build[4] — extra_body support for provider-specific request fields.

RapidAI/grok-build-desktop[5] — Tauri desktop GUI client.

mazdak/grok-build[6] — theming (Catppuccin).

thomas9120/grok-build-archival[7] — Windows telemetry-disable script.

saqoah/grok-build[8] — Kotlin MemoryBackend.

These are all pointless forks, they will die in a year.
