Private groups often use hosted team chat even when they do not want a central provider controlling servers, metadata, or access. That creates a trust gap for activist groups, sensitive communities, and teams working under privacy constraints.

Quiet can replace Slack for small groups prioritizing privacy, but it is not meant to match Slack's full business workspace ecosystem.
