Backstory Why This is the communication platform that is primarily used to communicate and coordinate with everyone within Extinction Rebellion.This platform was set up to replace Slack, such that XR teams can organise themselves privately, on non-commercial,non-US-government-accessible, community-owned-and-operated infrastructure - all protected under strict Swiss data-privacy laws.Furthermore, this server runs directly from renewable energy, making it mission coherent with XR as a whole.
