I recently went through these exact pains trying to contribute to a project that exclusively ran through Discord and eventually had to give up when it was clear they would never enable issues in their GitHub repos for “reasons.”
It was impossible to discover the history behind anything. Even current information was lost within days, having to rehash aspects that were already investigated and decided upon.
If xAI disappeared tomorrow, literally nothing of value would have been lost. I’m not sure who would even notice immediately as I still have never met a single human being in real life who personally uses X.
